- Add comprehensive server entry fields: name, description, tags, homepage, docs
- Remove legacy format compatibility logic from extract_server_spec
- Implement data validation and filtering in get_servers_snapshot_for
- Add strict id consistency check in upsert_in_config_for
- Enhance import logic with defensive programming for corrupted data
