skills-update

When invoked, the skill:

1. Reads the locally-installed version from ~/.claude/skills/.skills-collection.json (written by install.sh).
2. Fetches the latest tag from the GitHub repo.
3. Compares the two semver strings.
4. If a newer version exists, fetches the CHANGELOG.md section for the new version and shows it to the user.
5. Asks for explicit confirmation via AskUserQuestion.
6. On approval, runs install.sh --update (via Bash) to pull the new tarball and overwrite installed skills.

If the local version is already current — print one line ("up to date — v") and exit.

The skill never updates without explicit user confirmation.
