- Add providerRef mock to insertContentTool and writeToFileTool tests
- Update mocks to include diagnosticsEnabled and diagnosticsDelayMs settings
- Fix test expectations to match new implementation with diagnostic configuration
- Resolves failing unit tests for insertContentTool.spec.ts and writeToFileTool.spec.ts
