Test Coverage Improvements

[MCPClaude]

The current test coverage for the codebase appears to have some gaps that should be addressed. Based on file analysis, there are 33 implementation files and 14 test files.

Specific areas for test coverage improvement:

1. AutoHotkey provider has limited test coverage, especially for the screen functionality which contains TODOs and placeholder implementations
2. The server.ts module contains critical SSE/transport functionality that would benefit from more thorough testing
3. The modular provider architecture could use integration tests to verify proper component interaction
4. No tests found for environment variable handling in config.ts

Recommended actions:

1. Add unit tests for all providers and implement coverage reporting
2. Create integration tests for the modular provider architecture
3. Add tests for error handling scenarios, especially in network code
4. Consider setting up automated test coverage reporting in CI/CD pipeline
