* fix: address code review feedback for MCP server management
- Fix OAuth secret preservation to avoid mutating input parameter
by creating a merged config copy in ServerConfigsDB.update()
- Improve error handling in getResourcePermissionsMap to propagate
critical errors instead of silently returning empty Map
- Extract duplicated MCP server filter logic by exposing selectableServers
from useMCPServerManager hook and using it in MCPSelect component
* test: Update PermissionService tests to throw errors on invalid resource types
- Changed the test for handling invalid resource types to ensure it throws an error instead of returning an empty permissions map.
- Updated the expectation to check for the specific error message when an invalid resource type is provided.
* feat: Implement retry logic for MCP server creation to handle race conditions
- Enhanced the createMCPServer method to include retry logic with exponential backoff for handling duplicate key errors during concurrent server creation.
- Updated tests to verify that all concurrent requests succeed and that unique server names are generated.
- Added a helper function to identify MongoDB duplicate key errors, improving error handling during server creation.
* refactor: StatusIcon to use CircleCheck for connected status
- Replaced the PlugZap icon with CircleCheck in the ConnectedStatusIcon component to better represent the connected state.
- Ensured consistent icon usage across the component for improved visual clarity.
* test: Update AccessControlService tests to throw errors on invalid resource types
- Modified the test for invalid resource types to ensure it throws an error with a specific message instead of returning an empty permissions map.
- This change enhances error handling and improves test coverage for the AccessControlService.
* fix: Update error message for missing server name in MCP server retrieval
- Changed the error message returned when the server name is not provided from 'MCP ID is required' to 'Server name is required' for better clarity and accuracy in the API response.

* refactor: Restructure MCP registry system with caching
- Split MCPServersRegistry into modular components:
- MCPServerInspector: handles server inspection and health checks
- MCPServersInitializer: manages server initialization logic
- MCPServersRegistry: simplified registry coordination

- RegistryStatusCache: distributed leader election state
- Add promise utilities (withTimeout) replacing Promise.race patterns
- Add comprehensive cache integration tests for all cache implementations
- Remove unused MCPManager.getAllToolFunctions method
* fix: Update OAuth flow to include user-specific headers
* chore: Update Jest configuration to ignore additional test files
- Added patterns to ignore files ending with .helper.ts and .helper.d.ts in testPathIgnorePatterns for cleaner test runs.
* fix: oauth headers in callback
* chore: Update Jest testPathIgnorePatterns to exclude helper files
- Modified testPathIgnorePatterns in package.json to ignore files ending with .helper.ts and .helper.d.ts for cleaner test execution.
* ci: update test mocks

- Fixed a bug in reinitMCPServer where a user connection was created for an app-level server whenever this server is reinitialized
- Made MCPManager.getUserConnection to return an error if the connection is app-level
- Add MCPManager.getConnection to return either an app connection or a user connection based on the serverName
- Made MCPManager.appConnections public to avoid unnecessary wrapper methods.
