feat: Add streamable HTTP transport and remove unused tests
- Deleted unused test_simple_validation.py file
- Removed syntax/import validation tests (handled by linting)
- Added support for streamable HTTP transport mode
- Updated transport options: sse (default), stdio, http
- Fixed server default to SSE as intended
Transport modes now available:
- SSE: Server-Sent Events for web clients (default)
- stdio: Standard I/O for MCP protocol
- http: Streamable HTTP for modern clients
