chore: Enhance MCP server execution and compatibility with Cursor mode

- Introduce environment variables for Cursor compatibility in silent-mcp.sh and npx-entry.cjs
- Implement process cleanup for existing MCP instances to prevent conflicts
- Adjust logging behavior based on execution context to ensure proper message handling
- Add test-cursor.sh script to simulate Cursor environment for testing purposes
- Refactor stdio-server.ts to manage logging and message flushing based on compatibility mode
