fix: refactor MCP server

[luanfreitasdev]

This pull request introduces a major refactor to the MCP server management and its UI integration. The MCP server is now managed as a native Node.js instance within the Electron app, replacing the previous child process spawn approach. The UI receives a new, reactive MCP status indicator component, improving user feedback and error handling. Several improvements are made to project/environment switching logic for robustness.

MCP Server Management Refactor:

• Replaced child process spawning logic in src/main/mcp-manager.ts with direct instantiation and management of the MCP server using the new createMcpServer API, enabling better integration, logging, and lifecycle management. [1] [2] [3]
• Added system info logging and enhanced error handling/reporting for MCP server startup, shutdown, and status checks. Status is now broadcast to renderer windows.

MCP Server API and Initialization:

• Introduced createMcpServer and McpServerInstance in src/mcp-server/index.ts, supporting both HTTP and stdio modes, structured logging, and clean shutdown. Standalone script execution is supported for desktop usage. [1] [2]

UI Integration and Status Indicator:

• Replaced the old static MCP indicator in TheNavBar.vue with a new reactive NavBarMCP.vue component, which displays real-time MCP status, errors, and allows navigation to relevant settings or logs. [1] [2] [3]

Project/Environment Switcher Robustness:

• Improved logic in NavBarProjectSwitcher.vue to prevent errors when project/environment info is missing, ensuring safer state updates and persistence. [1] [2] [3] [4]

Minor Typing Improvements:

• Added explicit TypeScript language attribute to NavBarAlwaysOnTop.vue for improved type checking.
