feat(opencode-go): route qwen3.7-max via anthropic_messages

qwen3.7-max on OpenCode Go rejects the OpenAI-compatible (oa-compat)
format with HTTP 401 but works correctly via the Anthropic Messages
endpoint (/v1/messages with x-api-key auth).  Route it the same way
MiniMax models are routed: anthropic_messages api_mode.

Changes:
- hermes_cli/models.py: add qwen3.7-max routing + curated list
- hermes_cli/setup.py: add to setup wizard model list
- hermes_cli/auth.py: update provider comment
- tests: add assertions for qwen3.7-max api_mode routing
