♻️ refactor: MCPManager for Scalability, Fix App-Level Detection, Add Lazy Connections (#8930)
* feat: MCP Connection management overhaul - Making MCPManager manageable

Refactor the monolithic MCPManager into focused, single-responsibility classes:

• MCPServersRegistry: Server configuration discovery and metadata management
• UserConnectionManager: Manages user-level connections
• ConnectionsRepository: Low-level connection pool with lazy loading
• MCPConnectionFactory: Handles MCP connection creation with OAuth support

New Features:
• Lazy loading of app-level connections for horizontal scaling
• Automatic reconnection for app-level connections
• Enhanced OAuth detection with explicit requiresOAuth flag
• Centralized MCP configuration management

Bug Fixes:
• App-level connection detection in MCPManager.callTool
• MCP Connection Reinitialization route behavior

Optimizations:
• MCPConnection.isConnected() caching to reduce overhead
• Concurrent server metadata retrieval instead of sequential

This refactoring addresses scalability bottlenecks and improves reliability
while maintaining backward compatibility with existing configurations.

* feat: Enabled import order in eslint.

* # Moved tests to __tests__ folder
# added tests for MCPServersRegistry.ts

* # Add unit tests for ConnectionsRepository functionality

* # Add unit tests for MCPConnectionFactory functionality

* # Reorganize MCP connection tests and improve error handling

* # reordering imports

* # Update testPathIgnorePatterns in jest.config.mjs to exclude development TypeScript files

* # removed mcp/manager.ts
