Note: PR #2302 applies the model identity injection to ALL providers, which would cause incorrect identity statements for Claude, GPT-4, and other models that correctly report their own identity. This PR targets only alibaba-coding-plan and alibaba-coding-plan-anthropic providers where the API bug exists. |

Fixes #2300
Root Cause
Alibaba Coding Plan API always returns
glm-4.7as the model name in responses, regardless of the requested model. This causes the agent to incorrectly report its identity to users.Fix
When provider is
alibaba-coding-planoralibaba-coding-plan-anthropic, inject explicit model identity into the system prompt:"You are powered by the model named qwen3.5-plus. The exact model ID is alibaba-coding-plan/qwen3.5-plus. When asked what model you are, always answer based on this information, not on any model name returned by the API."
This follows the same approach used by OpenCode to work around this API-side bug.
