Phase 4 Batch 2: Tool Timeout Enforcement

Changes

1. Filesystem Tool Timeouts

  • FilesystemReadTool: Added 30s timeout for fs.stat and fs.readFile
  • FilesystemWriteTool: Added 30s timeout for fs.mkdir and atomic write
  • Uses Promise.race() for timeout enforcement

2. Pipeline-Level Timeout

  • ToolExecutionPipelineImpl: Added 60s timeout for all tool executions
  • Uses createTimeoutController with AbortController
  • Proper cleanup on completion

3. Timeout Configuration

  • Filesystem tools: 30 seconds (configurable)
  • Pipeline: 60 seconds (configurable)
  • Git tools: Already have 30s timeout
  • Shell tools: Already have 60s timeout

Testing

  • ✅ Local typecheck passed (54/54)
  • ✅ Local build passed (42/42)
  • ✅ Local test passed (85/85)
