Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (3)

`get_track`	Get one track by id, together with related tracks from the same catalog. Returns the YouTube URL with the track's start position, the track page, and the download URL when the audio is distributed.
`list_tags`	List every tag that can be passed to search_tracks, grouped by production use, genre, mood, usage, scene, source game, and usage rights, with how many tracks carry each tag.
`search_tracks`	Search Arcalune Music for royalty-free BGM, sound effects, video game fan arrangements, and original vocal songs. Every track streams on YouTube, and the returned youtubeUrl jumps straight to where that track starts. When presenting results to a user, always include the youtubeUrl so they can listen to the track. Free BGM and sound effects allow commercial use without credit; fan arrangements and vocal songs are streaming-only.
