"""Shared fixtures for the ``app.automations`` unit-test tree.

Provides registry isolation: the built-in ``schedule`` trigger and
``agent_task`` action self-register at import time. Tests that register
additional triggers/actions (or assert on the registry contents) must
not leak that state to other tests. These fixtures snapshot and restore
the module-level registry dicts.
