Merge branch 'feat/cobra'

Replace docopt-go with spf13/cobra, giving cheat a built-in
`--completion` flag that dynamically generates shell completions for
bash, zsh, fish, and powershell. This replaces the manually-maintained
static completion scripts and resolves the root cause of multiple
completion issues (#768, #705, #633, #632, #476).

-// Package cheatpath manages collections of cheat sheets organized in filesystem directories.
-//
-// A Cheatpath represents a directory containing cheat sheets, with associated
-// metadata such as tags and read-only status. Multiple cheatpaths can be
-// configured to organize sheets from different sources (personal, community, work, etc.).
-//
-// # Cheatpath Structure
-//
-// Each cheatpath has:
-//   - Name: A friendly identifier (e.g., "personal", "community")
-//   - Path: The filesystem path to the directory
-//   - Tags: Tags automatically applied to all sheets in this path
-//   - ReadOnly: Whether sheets in this path can be modified
-//
-// Example configuration:
-//
-//	cheatpaths:
-//	  - name: personal
-//	    path: ~/cheat
-//	    tags: []
-//	    readonly: false
-//	  - name: community
-//	    path: ~/cheat/community
-//	    tags: [community]
-//	    readonly: true
-//
-// # Directory-Scoped Cheatpaths
-//
-// The package supports directory-scoped cheatpaths via `.cheat` directories.
-// When running cheat, the tool walks upward from the current working directory
-// to the filesystem root, stopping at the first `.cheat` directory found. That
-// directory is temporarily added to the available cheatpaths.
-//
-// # Precedence and Overrides
-//
-// When multiple cheatpaths contain a sheet with the same name, the sheet
-// from the most "local" cheatpath takes precedence. This allows users to
-// override community sheets with personal versions.
-//
-// Key Functions
-//
-//   - Filter: Filters cheatpaths by name
-//   - Validate: Ensures cheatpath configuration is valid
-//   - Writeable: Returns the first writeable cheatpath
-//
-// Example Usage
-//
-//	// Filter cheatpaths to only "personal"
-//	filtered, err := cheatpath.Filter(paths, "personal")
-//	if err != nil {
-//	    log.Fatal(err)
-//	}
-//
-//	// Find a writeable cheatpath
-//	writeable, err := cheatpath.Writeable(paths)
-//	if err != nil {
-//	    log.Fatal(err)
-//	}
-//
-//	// Validate cheatpath configuration
-//	if err := cheatpath.Validate(paths); err != nil {

-// Package config manages application configuration and settings.
-//
-// The config package provides functionality to:
-//   - Load configuration from YAML files
-//   - Validate configuration values
-//   - Manage platform-specific configuration paths
-//   - Handle editor and pager settings
-//   - Configure colorization and formatting options
-//
-// # Configuration Structure
-//
-// The main configuration file (conf.yml) contains:
-//   - Editor preferences
-//   - Pager settings
-//   - Colorization options
-//   - Cheatpath definitions
-//   - Formatting preferences
-//
-// Example configuration:
-//
-//	---
-//	editor: vim
-//	colorize: true
-//	style: monokai
-//	formatter: terminal256
-//	pager: less -FRX
-//	cheatpaths:

-//	    path: ~/cheat/.cheat
-//	    tags: [community]

-//
-// # Platform-Specific Paths
-//
-// The package automatically detects configuration paths based on the operating system:
-//   - Linux/Unix: $XDG_CONFIG_HOME/cheat/conf.yml or ~/.config/cheat/conf.yml
-//   - macOS: ~/Library/Application Support/cheat/conf.yml
-//   - Windows: %APPDATA%\cheat\conf.yml
-//
-// # Environment Variables
-//
-// The following environment variables are respected:
-//   - CHEAT_CONFIG_PATH: Override the configuration file location
-//   - CHEAT_USE_FZF: Enable fzf integration when set to "true"
-//   - EDITOR: Default editor if not specified in config
-//   - VISUAL: Fallback editor if EDITOR is not set

-// Package display handles output formatting and presentation for the cheat application.
-//
-// The display package provides utilities for:
-//   - Writing output to stdout or a pager
-//   - Formatting text with indentation
-//   - Creating faint (dimmed) text for de-emphasis
-//   - Managing colored output
-//
-// # Pager Integration
-//
-// The package integrates with system pagers (less, more, etc.) to handle
-// long output. If a pager is configured and the output is to a terminal,
-// content is automatically piped through the pager.
-//
-// # Text Formatting
-//
-// Various formatting utilities are provided:
-//   - Faint: Creates dimmed text using ANSI escape codes
-//   - Indent: Adds consistent indentation to text blocks
-//   - Write: Intelligent output that uses stdout or pager as appropriate
-//
-// Example Usage
-//
-//	// Write output, using pager if configured
-//	if err := display.Write(output, config); err != nil {
-//	    log.Fatal(err)
-//	}
-//
-//	// Create faint text for de-emphasis
-//	fainted := display.Faint("(read-only)", config)
-//
-//	// Indent a block of text
-//	indented := display.Indent(text, "  ")
-//
-// # Color Support
-//
-// The package respects the colorization settings from the config.
-// When colorization is disabled, formatting functions like Faint
-// return unmodified text.
-//
-// # Terminal Detection
-//
-// The package uses isatty to detect if output is to a terminal,
-// which affects decisions about using a pager and applying colors.

-// Package sheet provides functionality for parsing and managing individual cheat sheets.
-//
-// A sheet represents a single cheatsheet file containing helpful commands, notes,
-// or documentation. Sheets can include optional YAML frontmatter for metadata
-// such as tags and syntax highlighting preferences.
-//
-// # Sheet Format
-//
-// Sheets are plain text files that may begin with YAML frontmatter:
-//
-//	---
-//	syntax: bash
-//	tags: [networking, linux, ssh]
-//	---
-//	# Connect to remote server
-//	ssh user@hostname
-//
-//	# Copy files over SSH
-//	scp local_file user@hostname:/remote/path
-//
-// The frontmatter is optional. If omitted, the sheet will use default values.
-//
-// # Core Types
-//
-// The Sheet type contains:
-//   - Title: The sheet's name (derived from filename)
-//   - Path: Full filesystem path to the sheet
-//   - Text: The content of the sheet (without frontmatter)
-//   - Tags: Categories assigned to the sheet
-//   - Syntax: Language hint for syntax highlighting
-//   - ReadOnly: Whether the sheet can be modified
-//
-// Key Functions
-//
-//   - New: Creates a new Sheet from a file path
-//   - Parse: Extracts frontmatter and content from sheet text
-//   - Search: Searches sheet content using regular expressions
-//   - Colorize: Applies syntax highlighting to sheet content
-//
-// # Syntax Highlighting
-//
-// The package integrates with the Chroma library to provide syntax highlighting.
-// Supported languages include bash, python, go, javascript, and many others.
-// The syntax can be specified in the frontmatter or auto-detected.
-//
-// Example Usage
-//
-//	// Load a sheet from disk
-//	s, err := sheet.New("/path/to/sheet", []string{"personal"}, false)
-//	if err != nil {
-//	    log.Fatal(err)
-//	}
-//
-//	// Search for content
-//	matches, err := s.Search("ssh", false)
-//	if err != nil {
-//	    log.Fatal(err)
-//	}
-//
-//	// Apply syntax highlighting
-//	colorized, err := s.Colorize(config)

-//   - Load sheets from multiple cheatpaths
-//   - Consolidate duplicate sheets (with precedence rules)
-//   - Filter sheets by tags
-//   - Sort sheets alphabetically
-//   - Extract unique tags across all sheets
-//
-// # Loading Sheets
-//
-// Sheets are loaded recursively from cheatpath directories, excluding:
-//   - Hidden files (starting with .)
-//   - Files in .git directories
-//   - Files with extensions (sheets have no extension)
-//
-// # Consolidation
-//
-// When multiple cheatpaths contain sheets with the same name, consolidation
-// rules apply based on the order of cheatpaths. Sheets from earlier paths
-// override those from later paths, allowing personal sheets to override
-// community sheets.
-//
-// Example:
-//
-//	cheatpaths:
-//	  1. personal: ~/cheat
-//	  2. community: ~/cheat/community
-//
-//	If both contain "git", the version from "personal" is used.
-//
-// # Filtering
-//
-// Sheets can be filtered by:
-//   - Tags: Include only sheets with specific tags
-//   - Cheatpath: Include only sheets from specific paths
-//
-// Key Functions
-//
-//   - Load: Loads all sheets from the given cheatpaths
-//   - Filter: Filters sheets by tag
-//   - Consolidate: Merges sheets from multiple paths with precedence

-
-An implementation of [docopt](http://docopt.org/) in the [Go](http://golang.org/) programming language.
-
-**docopt** helps you create *beautiful* command-line interfaces easily:
-
-```go
-package main
-
-import (
-	"fmt"
-	"github.com/docopt/docopt-go"
-)
-
-func main() {
-	  usage := `Naval Fate.
-
-Usage:
-  naval_fate ship new <name>...
-  naval_fate ship <name> move <x> <y> [--speed=<kn>]
-  naval_fate ship shoot <x> <y>
-  naval_fate mine (set|remove) <x> <y> [--moored|--drifting]
-  naval_fate -h | --help
-  naval_fate --version
-
-Options:
-  -h --help     Show this screen.
-  --version     Show version.
-  --speed=<kn>  Speed in knots [default: 10].
-  --moored      Moored (anchored) mine.
-  --drifting    Drifting mine.`
-
-	  arguments, _ := docopt.ParseDoc(usage)
-	  fmt.Println(arguments)
-}
-```
-
-**docopt** parses command-line arguments based on a help message. Don't write parser code: a good help message already has all the necessary information in it.
-
-## Installation
-
-⚠ Use the alias "docopt-go". To use docopt in your Go code:
-
-```go
-import "github.com/docopt/docopt-go"
-```
-
-To install docopt in your `$GOPATH`:
-
-```console
-$ go get github.com/docopt/docopt-go
-```
-
-## API
-
-Given a conventional command-line help message, docopt processes the arguments. See https://github.com/docopt/docopt#help-message-format for a description of the help message format.
-
-This package exposes three different APIs, depending on the level of control required. The first, simplest way to parse your docopt usage is to just call:
-
-```go
-docopt.ParseDoc(usage)
-```
-
-This will use `os.Args[1:]` as the argv slice, and use the default parser options. If you want to provide your own version string and args, then use:
-
-```go
-docopt.ParseArgs(usage, argv, "1.2.3")
-```
-
-If the last parameter (version) is a non-empty string, it will be printed when `--version` is given in the argv slice. Finally, we can instantiate our own `docopt.Parser` which gives us control over how things like help messages are printed and whether to exit after displaying usage messages, etc.
-
-```go
-parser := &docopt.Parser{
-  HelpHandler: docopt.PrintHelpOnly,
-  OptionsFirst: true,
-}
-opts, err := parser.ParseArgs(usage, argv, "")
-```
-
-In particular, setting your own custom `HelpHandler` function makes unit testing your own docs with example command line invocations much more enjoyable.
-
-All three of these return a map of option names to the values parsed from argv, and an error or nil. You can get the values using the helpers, or just treat it as a regular map:
-
-```go
-flag, _ := opts.Bool("--flag")
-secs, _ := opts.Int("<seconds>")
-```
-
-Additionally, you can `Bind` these to a struct, assigning option values to the
-exported fields of that struct, all at once.
-
-```go
-var config struct {

-More documentation is available at [godoc.org](https://godoc.org/github.com/docopt/docopt-go).
-
-## Unit Testing
-
-Unit testing your own usage docs is recommended, so you can be sure that for a given command line invocation, the expected options are set. An example of how to do this is [in the examples folder](examples/unit_test/unit_test.go).
-
-## Tests
-
-All tests from the Python version are implemented and passing at [Travis CI](https://travis-ci.org/docopt/docopt-go). New language-agnostic tests have been added to [test_golang.docopt](test_golang.docopt).
-
-To run tests for docopt-go, use `go test`.

-Package docopt parses command-line arguments based on a help message.
-
-Given a conventional command-line help message, docopt processes the arguments.
-See https://github.com/docopt/docopt#help-message-format for a description of
-the help message format.
-
-This package exposes three different APIs, depending on the level of control
-required. The first, simplest way to parse your docopt usage is to just call:
-
-	docopt.ParseDoc(usage)
-
-This will use os.Args[1:] as the argv slice, and use the default parser
-options. If you want to provide your own version string and args, then use:
-
-	docopt.ParseArgs(usage, argv, "1.2.3")
-
-If the last parameter (version) is a non-empty string, it will be printed when
---version is given in the argv slice. Finally, we can instantiate our own
-docopt.Parser which gives us control over how things like help messages are
-printed and whether to exit after displaying usage messages, etc.
-
-	parser := &docopt.Parser{
-		HelpHandler: docopt.PrintHelpOnly,
-		OptionsFirst: true,
-	}
-	opts, err := parser.ParseArgs(usage, argv, "")
-
-In particular, setting your own custom HelpHandler function makes unit testing
-your own docs with example command line invocations much more enjoyable.
-
-All three of these return a map of option names to the values parsed from argv,
-and an error or nil. You can get the values using the helpers, or just treat it
-as a regular map:
-
-	flag, _ := opts.Bool("--flag")
-	secs, _ := opts.Int("<seconds>")
-
-Additionally, you can `Bind` these to a struct, assigning option values to the
-exported fields of that struct, all at once.
-
-	var config struct {
-		Command string `docopt:"<cmd>"`
-		Tries   int    `docopt:"-n"`
-		Force   bool   // Gets the value of --force
-	}
-	opts.Bind(&config)
