v0.12.236 — MiniMax M3 vision flag (live-probed)

Fixed — vision missing on MiniMax M3

• minimax/minimax-m3 was registered without vision, so filterByVision() dropped it from the candidate pool whenever a request carried an image_url content part. blockrun's catalog lists M3 as chat+reasoning+coding with no vision category, but that is the same upstream under-claim class as claude-haiku-4.5/claude-sonnet-4.6 (see v0.12.235): a live gateway probe on 2026-08-02 sent a two-color image to M3 and it described both colors and their positions correctly. minimax-m2.7 is text-only upstream and stays without the flag; a regression test pins both. (#226)

Notes

• Rejected in review, not merged: a proposed switch of the music default to minimax/music-3.0 (#227). blockrun's gateway registers only minimax/music-2.5+ and rejects unknown audio model ids with 400, so the new default would have failed every music request. The mock-upstream e2e suite cannot catch invalid gateway ids — it accepts any model string.
