Says that a call is still running, to a client that asked to be told.

A wait can hold a request for a minute, and without this the client cannot
tell that from a server that has died — so it either shows nothing or gives
up. MCP's answer is `notifications/progress`, which a client opts into by
putting a `progressToken` in a request's `_meta`. Measured against the Codex
CLI, which sends one on every `tools/call`.

Silent when no token was sent: an unsolicited notification is a protocol
error, not a courtesy.
