"""Regression test for #54167 — stale platform lock must be retryable.
When a gateway process is killed (SIGKILL, crash) during Telegram
initialization, the scoped lock file survives. On next startup,
``acquire_scoped_lock()`` detects the stale lock and deletes it, but may
still return ``(False, existing_dict)`` to the caller (e.g. if the
unlink fails due to permissions, or a race condition lets another
process grab the lock first).
``_acquire_platform_lock()`` must mark such failures as **retryable**
so the reconnect watcher can retry after a delay — not permanently kill
the platform.
Contract asserted here
----------------------
``_set_fatal_error`` is called with ``retryable=True`` when lock
acquisition fails, regardless of the reason.
