Browse Source 
Add Kimi K2.5 and Kimi K2.5 Free to the OpenCode Zen model catalog.

- Add aliases: kimi -> kimi-k2.5, kimi-free -> kimi-k2.5-free
- Both models use anthropic-messages API
- 256k context window, 8192 max tokens
- No image input support (like other Kimi/MiniMax models)
- Free tier pricing (0 input/output)
- Update static fallback models list
