Subject: [PATCH] feat: add LiteLLM provider support for model name remapping

LiteLLM proxy expects plain model IDs without the provider prefix.
This change strips the 'litellm/' prefix from model names before
sending API requests, following the same pattern as zai-coding-plan.

Example:
- Spacebot config: channel = "litellm/kimi-k2p5"
- API request: {"model": "kimi-k2p5"}

Tested with dev instance:
- 60+ successful API calls
- All 6 agents generating profiles correctly
- Fallback chains working as expected

Fixes: model routing with LiteLLM proxy gateway
