Subject: [PATCH] feat(minimax): add MiniMax-M3 video input capability to model
 cost map

Mark minimax/MiniMax-M3 with supports_video_input=true in both the
bundled backup cost map and the root cost map so the documented video
input modality is advertised alongside the existing supports_vision
flag. Add regression tests covering the capability and provider.
