fix: Remove redundant tests and correct default transport mode

- Changed default transport from 'stdio' to 'sse' as intended
- Removed redundant syntax_validation and import_validation tests (handled by linting)
- Clarified test_integration.py is for HTTP/SSE mode testing
- Simplified test_simple_validation.py to only test server startup

The server now correctly defaults to SSE (Server-Sent Events) mode for HTTP
transport, with stdio as an alternative for MCP protocol communication.
