Cleanup of project files:
- Remove CALIBRE_OPF_IMPLEMENTATION.md (obsolete documentation)
- Remove Bruno API collection files for field value searches:
- Field Values Search - Authors.yml
- Field Values Search - Genres.yml
- Field Values Search - Languages.yml
- Field Values Search - Series.yml
These files are no longer needed as the functionality has been
implemented and the API has evolved.
