feat(patrol): add backoff test formula and fix await-signal

Browse Source 
Add mol-backoff-test formula for integration testing exponential backoff
with short intervals (2s base, 10s max) to observe multiple cycles quickly.

Fix await-signal to use --since 1s when subscribing to activity feed.
Without this, historical events would immediately wake the signal,
preventing proper timeout and backoff behavior.
