Connect configured MCP servers in per-server child scopes at layer boot,
tracking status and a startup deferred per server. Query methods wait for
the relevant server(s) to finish startup before serving.
Drop the in-memory connect/disconnect/add overrides; runtime enable/disable
will come later through config updates. List methods (tools/instructions/
prompts/resourceCatalog) are aggregate across all servers with per-item
provenance; prompt/readResource stay server-scoped for routing.
Add a Connection abstraction in client.ts so the SDK Client never leaks
into the rest of core.
