🔒 feat: Idempotency Check for OAuth Flow Completion (#10468)
* 🔒 feat: Implement idempotency check for OAuth flow completion

- Added a check to prevent duplicate token exchanges if the OAuth flow has already been completed.
- Updated the OAuth callback route to redirect appropriately when a completed flow is detected.
- Refactored token storage logic to use original flow state credentials instead of updated ones.
- Enhanced tests to cover the new idempotency behavior and ensure correct handling of OAuth flow states.

* chore: add back scope for logging

* refactor: Add isFlowStale method to FlowStateManager for stale flow detection

- Implemented a new method to check if a flow is stale based on its age and status.
- Updated MCPConnectionFactory to utilize the isFlowStale method for cleaning up stale OAuth flows.
- Enhanced logging to provide more informative messages regarding flow status and age during cleanup.

* test: Add unit tests for isFlowStale method in FlowStateManager

- Implemented comprehensive tests for the isFlowStale method to verify its behavior across various flow statuses (PENDING, COMPLETED, FAILED) and age thresholds.
- Ensured correct handling of edge cases, including flows with missing timestamps and custom stale thresholds.
- Enhanced test coverage to validate the logic for determining flow staleness based on createdAt, completedAt, and failedAt timestamps.

* 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
- Add distributed caching layer:
  - ServerConfigsCacheRedis: Redis-backed configuration cache
  - ServerConfigsCacheInMemory: in-memory fallback cache
  - 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

♻️ 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
