Subject: [PATCH] fix(api): remove unsupported 'user' param from FC/ReAct
 invoke_llm calls

FunctionCallStrategy and ReActStrategy were passing user=self.context.user_id
to ModelInstance.invoke_llm() which doesn't accept that parameter.
This caused tool-using agent runs to fail with:
  "ModelInstance.invoke_llm() got an unexpected keyword argument 'user'"

Verified: Agent V2 with current_time tool now works end-to-end:
  ROUND 1: LLM thought -> CALL current_time -> got time
  ROUND 2: LLM generates answer with time info
Made-with: Cursor
