Item-shaped results now omit empty fields and drop low-value metadata
(overview, lyrics, file_path, creation_date, premiere_date, bitrate);
absent numeric fields drop the key instead of emitting "". Player
sessions report hh:mm:ss times only; playlists drop overview/date_created.
The lyrics_or_description search parameter is removed, along with the
unused DTO fields, and upstream Fields requests are slimmed to match.
Module path renamed to git.i3omb.com/gronod/emby-mcp.
