feat(skill): add database migration and Gemini support for multi-app skills

- Refactor skills table from single key to (directory, app_type) composite primary key
- Add migration logic to convert existing skill records
- Support skill installation/uninstallation for Claude/Codex/Gemini independently
- Add new Tauri commands: get_skills_for_app, install_skill_for_app, uninstall_skill_for_app
- Update frontend API and components to support app-specific skill operations
