> POST /v1/sessions/chat and POST /v1/sessions/chat/voice are gone; create a chat thread as an ordinary session with POST /v1/sessions instead.

The two endpoints that looked up a per-user Platform Chat session by tag are removed. A chat thread is now an ordinary session created with `POST /v1/sessions` and bound to an agent.

After upgrading, `POST /v1/sessions/chat` returns `405` and `POST /v1/sessions/chat/voice` returns `404`. Sessions already tagged `global-chat` stay listed and readable through the normal session routes, and the Platform Chat harness is unchanged.
