"""Live smoke test for the KQ support booking tool API.

Reads KQ_PB_URL and KQ_TOOL_TOKEN from the environment. Never prints the token.
Assumes at least one open future support slot exists (created by Ale during
deployment). Safe to run against the live PocketBase: it only creates idempotent
test holds for a fixed test conversation id.
