/**
|
|
* The minimal `createMcpHandler` deployment, on its default posture.
|
|
*
|
|
* One factory, one endpoint: 2026-07-28 traffic is served per request, and
|
|
* 2025-era (non-envelope) traffic is served stateless from the same factory
|
|
* (`legacy: 'stateless'`, the default). This replaces the hand-wired
|
|
* "new transport + new server per POST" stateless idiom of the 1.x SDK with
|
|
* a one-liner.
|
|
*
|
|
* HTTP-only — `createMcpHandler`'s `legacy: 'stateless'` posture is an HTTP
|
|
* hosting concern; a stdio leg would bypass it. See `dual-era/` for the stdio
|
|
* analogue.
