implement-hooks

Build or update hooks/hooks.json and related script handlers with deterministic validation.

Workflow

1. Identify required hook event(s), matcher(s), and hook type(s).
2. Implement hooks/hooks.json using stable ${CLAUDE_PLUGIN_ROOT} paths.
3. Add or update hook handler scripts and mark them executable.
4. Run hook validation and script smoke tests.
5. Verify plugin-level integration from implement-plugin and cross-check in plugin-verification.
