- C-1: Add event_sender: None to ToolContext in file_write.rs and
  file_read.rs test helper functions (compilation fix)
- I-1: file_write tool now echoes content preview in output JSON,
  enabling streamStore.ts artifact auto-creation pipeline to work
- S-2: Fix typo "LLM 锥应错误" → "LLM 响应错误" in loop_runner.rs
