"""Regression guard for #62151 — gateway cron must not wedge on the 2nd+ call.

Gateway-fired cron jobs hung forever on the 2nd+ API call because both the
non-streaming (``interruptible_api_call``) and the default streaming
(``interruptible_streaming_api_call``) paths run the request on a spawned
daemon worker thread. Inside the gateway's nested cron thread pools that extra
worker wedged before the socket opened; the same job succeeded via ``hermes
cron tick`` (foreground, no nested pools). Cron has no interactive interrupt
surface, so both paths now run inline on the conversation thread for the
``cron`` platform.

These tests pin: (1) the inline gate is cron-only, (2) the inline call runs on
the *calling* thread — no worker is spawned — for both entry points, and (3)
the shared dispatch closes the per-request client.
