feat(opencode-go): align Go models with official endpoints

Update OpenCode Go model catalog to match the official Go docs.
Route Qwen 3.7 and MiniMax models through /v1/messages with
Anthropic-compatible headers instead of OpenAI-compatible chat.
Keep GLM, Kimi, DeepSeek, and MiMo on /chat/completions; use
kimi-k2.7-code because the live Go API rejects kimi-k2.7 for chat
while the docs config example uses the code model ID.
