chore(skills): tea-comment @filepath support and docs update

tea-comment now accepts @/path/to/file.md syntax to read comment body
from a file, avoiding $() subshells that break permission matching.
Updated pr-review skill and tea-cli rules with the new pattern.

 - **All flags must be explicit** — omitting `--login` or `--repo` triggers interactive prompts that crash in Claude Code (no TTY)
 - **Use `--output simple`** for machine-readable output (no table borders)
-- **For comments, use `tooling/tea-comment <number> "body"`** — handles temp files and cleanup automatically. Works with multi-line strings.
+- **For comments, use `tooling/tea-comment <number> @/tmp/file.md`** for long comments (write to file first, then pass `@filepath`). Short inline strings also work: `tooling/tea-comment <number> "body"`. The `@filepath` form avoids `$()` subshells which break permission matching.
 - **`tea pr reject` does not work on your own PRs** — use `tea comment` instead
 - **Never delete protected branches:** `main`, `maintenance`, `server`, `client`, `copy`, `audio`, `visual`, `ci` are protected on Gitea. Do not use `tea pr clean`, `git push --delete`, or `git branch -D` on these branches.
