feat(skills): add search functionality to Skills page

- Add search input with Search icon in SkillsPage component
- Implement useMemo-based filtering by skill name, description, and directory
- Display search results count when filtering is active
- Show "no results" message when no skills match the search query
- Add i18n translations for search UI (zh/en)
- Maintain responsive layout and consistent styling with existing UI
