Review summary

This focused MiniMax update moves the defaults to music-3.0 and adds response decoding coverage. The scope is small, but the asynchronous response path is not complete.

Important — handle in-progress responses instead of treating them as terminal failures

data.status == 1 is now returned as MiniMax music generation is still in progress, but the provider does not retain a task/job identifier or poll the provider before failing. For an asynchronous generation request this makes a normal accepted/in-progress response an unavoidable user-visible failure; the new test locks that failure in as expected behavior.

Please implement the documented completion flow (capture the task identifier and poll/retry until success/cancellation/context deadline), or confirm with an API fixture that this endpoint is synchronous and cannot return status 1 for a valid request. Add coverage for the eventual-success path.

Verdict: Request changes — the async lifecycle must be handled before this can reliably serve music generation.
