Disambiguate play_music vs queue_music by verb, not content type

queue_music's tool description explains at length that playlists/
albums/artists auto-play instead of queueing, and the small model was
using that as a signal to route ANY playlist/genre request through
queue_music -- even ones that said "play". Verified: "play jazz in
the bedroom" called queue_music 0/5 reps before this change (and in
the opaque-ID room variant), 5/5 play_music after, with no
regressions across the rest of the suite (199/200, 39/40 reliable).

+This choice depends ONLY on the verb the user used ("play" vs "queue"/"add to queue"), never on the content type. A playlist or genre request that says "play" still calls play_music, not queue_music — queue_music's playlist/album/artist auto-play behavior only applies when the user actually said "queue"/"add to queue".

 RULE: if the request has the form "[title] by [artist]" (a specific song/album title followed by "by" and an artist name — no matter what words come before it, e.g. "play", "queue", "throw on", "put on", "the album", "the song"), the query is ONLY the title — always strip " by [artist]" from the end. Never include the word "by" or the artist name in the query for this pattern.
