Bob.Hou c40a5f0432 fix(build): externalize @modelcontextprotocol/sdk to heal MCP initialize 500 on standalone builds (#13859)
* build/mcp: externalize @modelcontextprotocol/sdk in standalone server bundle

The SDK client graph contains a module-level class-extends-Client cycle
against the top-level-await Client module. Webpack's TLA runtime evaluates
that circular subgraph out of order when it is inlined into route chunks,
throwing "Cannot access 'l' before initialization" during module
evaluation. Every request to /api/mcp/stream then answers HTTP 500 on
initialize and the failed module is evicted and re-evaluated per request,
which floods the logs with the same ReferenceError. Node's native ESM
loader resolves the same circular graph through live bindings, so keep
the SDK external to the server bundle like the other packages that break
only when bundled.
