refactor(skills): apply progressive disclosure to gitea skill

Split gitea skill into main file and reference documentation.
Main SKILL.md now focuses on core commands (154 lines, down from 201),
with setup/auth and CI/Actions moved to reference files.

 # Gitea CLI (tea)
 
-Command-line interface for interacting with Gitea repositories.
+Command-line interface for Gitea repositories. Use `tea` for issue/PR management in Gitea instances.
 
-## Installation
-
-```bash
-brew install tea
-```
-
-## Authentication
-
-The `tea` CLI authenticates via `tea logins add`. Credentials are stored locally by tea.
-
-```bash
-tea logins add                       # Interactive login
-tea logins add --url <url> --token <token> --name <name>  # Non-interactive
-tea logins list                      # Show configured logins
-tea logins default <name>            # Set default login
-```
-
-## Configuration
-
-Config is stored at `~/Library/Application Support/tea/config.yml` (macOS).
-
-To avoid needing `--login` on every command, set defaults:
-
-```yaml
-preferences:
-    editor: false
-    flag_defaults:
-        remote: origin
-        login: git.flowmade.one
-```
+**Setup required?** See [reference/setup.md](reference/setup.md) for installation and authentication.
 
 ## Repository Detection
 
 `tea` automatically detects the repository from git remotes when run inside a git repository. Use `--remote <name>` to specify which remote to use.
