feat: update database schema for search history and repository metadata

- Implement `MIGRATION_6_7` to create a new `search_history` table for storing search queries and timestamps.
- Update `MIGRATION_5_6` to include additional repository metadata in the `seen_repos` table, including name, owner info, description, language, and URL.
- Register `MIGRATION_6_7` in the database initialization logic.
