Bug Description

hermes doctor MiniMax health check fails with HTTP 404. The check uses https://api.minimax.io/v1/models and https://api.minimaxi.com/v1/models, but these endpoints do not exist.

Steps to Reproduce

1. Set MINIMAX_API_KEY in ~/.hermes/.env
2. Run hermes doctor
3. Observe: MiniMax shows ⚠ HTTP 404

Verified

• Tested all MiniMax endpoints directly — all return 404:

  • https://api.minimax.io/v1/models → 404
  • https://api.minimax.io/anthropic/v1/models → 404
  • https://api.minimax.io/api/paas/v4/models → 404
  • https://api.minimaxi.com/v1/models → 404

• The API key itself is valid (125 chars, sk-cp-...), actual MiniMax API calls work fine in hermes-agent.

Root Cause

Commit d442f25a (fix: align MiniMax provider with official API docs) changed the health check from None (disabled) to using https://api.minimax.io/v1/models. However this endpoint does not exist on MiniMax servers.

Expected Fix

Either:

1. Revert MiniMax health check to supports_health_check=False (like before d442f25), OR
2. Find the correct working /models endpoint for MiniMax API v2

Environment

• hermes-agent: v0.9.0 (2026.4.13)
• OS: macOS
• Python: 3.11.15
