Drop inline `commit-msg/SKILL.md` — now deployed
as a symlink from the central `ai.skillz` repo via
`deploy-skill.sh`.
Gitignore all symlinked skill dirs so they stay
machine-local:
- fully-symlinked: `py-codestyle`, `close-wkt`,
`open-wkt`, `plan-io`, `prompt-io`,
`code-review-changes`, `resolve-conflicts`,
`inter-skill-review`, `yt-url-lookup`
- hybrid (symlinked SKILL.md + references):
`commit-msg/SKILL.md`, `pr-msg/SKILL.md`,
`pr-msg/references`
