CLASP v0.59.0 doesn't handle Kimi-K2.5's reasoning_content field. Resolve Pls

[AI-Manditrade]

Kimi-K2.5 (Azure OpenAI) returns responses with:

• "reasoning_content": "The..." — the actual model output goes here
• "content": null — empty
• "finish_reason": "length" — it uses all tokens on reasoning

CLASP translates content → Anthropic text block, but content is null, so the response is empty. The reasoning_content field is silently dropped.

Fix options (all in CLASP):

1. CLASP should merge reasoning_content into content when translating OpenAI → Anthropic format
2. Or CLASP should send a parameter to disable Kimi-K2.5's reasoning mode (Azure API may support this)
