feat!: rebuild tea on Cobra with explicit noun/verb commands (#1126)

- **switch tea to the Cobra command tree:** `internal/app` wires the packages from parts 1–4 into explicit noun/verb commands with `--repo`, `--json` / `--jq`, `--sudo` and `--debug`; `main.go` points at it. Build, release and docs tooling (`tools/cli-docs`, Makefile, goreleaser, snap, CI) and README / CONTRIBUTING are updated.
- **remove the urfave/cli command tree:** deletes `cmd/`, `modules/`, the old integration tests, contrib completion scripts and the generated `docs/CLI.md`, and drops their dependencies. This commit only deletes.

## Breaking changes

This is a breaking release. It requires Gitea 28 or newer; configuration moves to separate `config.yml` and `hosts.yml` files and requires fresh authentication, and command names, aliases, flags and output formats change. `docs/migration-1.0.md` maps every old command, flag and environment variable to its replacement.
