fix: pre-build FTS5 index for Docker compatibility

- Add FTS5 pre-creation in fetch-templates.ts before data import
- Create prebuild-fts5.ts script to ensure FTS5 tables exist
- Improve logging in template-repository.ts for better debugging
- Add npm script 'prebuild:fts5' for manual FTS5 setup

This ensures template search works consistently in Docker mode
where runtime FTS5 table creation might fail due to permissions.
