refactor: clean up type casting in test files
- Created createMockConfiguration and createMockStorage helpers in test-helpers.ts- Replaced 'as any' casts with proper typed mocks in api.test.ts- Fixed fs.readdir type casting in storage.test.ts using 'as never'- Replaced manual mocks with helper functions for better type safety- Fixed vi.mocked() usage for fs.readFile and ProxyAgent🤖 Generated with [Claude Code](https://claude.ai/code)Co-Authored-By: Claude <noreply@anthropic.com>
