fix: refresh MiniMax model defaults

[octo-patch]

Replaces #431 with a clean commit history.

Summary

• Refresh the direct MiniMax defaults for MiniMax-M3 and MiniMax-M2.7, including context, modalities, thinking controls, and current pricing metadata.
• Preserve all MiniMax-M3 standard and priority pricing tiers while routing OpenAI- and Anthropic-compatible requests with protocol-correct thinking payloads.
• Document the international and China Base URLs for both supported protocols.
• Preserve non-JSON test-runner stdout frames while harness tests capture runtime JSONL events.
