Add tea actions runs and workflows commands (#880)

Implements comprehensive workflow execution tracking for Gitea Actions using tea CLI

## Features

### tea actions runs list
- List workflow runs with filtering (status, branch, event, actor, time)
- Time filters: relative (24h, 7d) and absolute dates
- Status symbols: ✓ success, ✘ failure, ⭮ pending, ⊘ skipped/cancelled, ⚠ blocked
- Multiple output formats: table, json, yaml, csv, tsv

### tea actions runs view
- View run details with metadata (ID, status, workflow, branch, event, trigger info)
- Shows jobs table with status, runner, duration
- Optional --jobs flag to toggle jobs display

### tea actions runs delete
- Delete/cancel workflow runs with confirmation prompt
- Supports --confirm/-y to skip prompt

### tea actions runs logs
- View job logs for all jobs or specific job (--job <id>)
- **New: --follow/-f flag for real-time log following** (like tail -f)
- Polls API every 2 seconds, only shows new content
- Auto-detects completion and exits

### tea actions workflows list
- List workflow files (.yml and .yaml) in repository
- Searches in .gitea/workflows and .github/workflows
- Shows active (✓) or inactive (✗) status based on recent runs
- Displays workflow name, path, and file size

## Commands

`tea actions runs list --status success --since 24h`
`tea actions runs view 123`
`tea actions runs delete 123 --confirm`
`tea actions runs logs 123 --job 456 --follow`

## Tests
