Real temp-HERMES_HOME tests for _broadcast_watched_changes: silent seed, cron/sessions signature moves, the 2s sessions floor's trailing edge, the pet signature staying 'off' without a renderable pet, meta payload on pet.changed, and a broken probe never killing the pass. Part of #73618.

"""The generalized change watcher (#73618): cheap on-disk signatures →
|
|
``pet.changed`` / ``cron.changed`` / ``sessions.changed`` global broadcasts.
|
|
|
|
Behavior contracts, exercised against a real temp HERMES_HOME (no mocks on the
|
|
filesystem path): first sighting seeds silently, a moved signature broadcasts
|
|
once, the sessions floor coalesces a write burst but keeps its trailing edge,
|
|
and the pet signature only moves for a *renderable* pet.
