Replace all console.error calls in MCP services with NestJS Logger
instances for consistent structured logging in production.
- mcp-hub.service.ts: Add Logger instance, replace console.error in
onModuleDestroy cleanup
- stdio-transport.ts: Add Logger instance, replace console.error for
stderr output (as warn) and JSON parse failures (as error)

Implement MCP Phase 1 infrastructure for agent tool integration with
central hub, tool registry, and STDIO transport layers.
Components:
- McpHubService: Central registry for MCP server lifecycle
- StdioTransport: STDIO process communication with JSON-RPC 2.0
- ToolRegistryService: Tool catalog management
- McpController: REST API for MCP management
Endpoints:
- GET/POST /mcp/servers - List/register servers
- POST /mcp/servers/:id/start|stop - Lifecycle control
- DELETE /mcp/servers/:id - Unregister
- GET /mcp/tools - List tools
- POST /mcp/tools/:name/invoke - Invoke tool
Features:
- Full JSON-RPC 2.0 protocol support
- Process lifecycle management
- Buffered message parsing
- Type-safe with no explicit any types
- Proper cleanup on shutdown
Tests: 85 passing with 90.9% coverage
