Ruling notice-retry-policy. The five-attempt cap and its terminal
"exhausted" state are gone. A failed entry is eligible again once
min(2^(attempts-1), 60) minutes have passed since its last journal
update; a run inside the delay skips it without spawning the bridge.
Every attempt keeps the same nonce. The exit status is non-zero while
any entry is unknown or has failed 3 or more times, and retries go on.
status shows nextEligibleAt for failed entries.
The clock is one now() that WATCHDOG_NOTICE_NOW_MS can override, like
the bridge timeout override, so tests drive the backoff without sleeping.
The process summary field "exhausted" is renamed "failing". A journal
entry whose updatedAt is not a date is now refused as
journal-entry-invalid, since the delay is measured from it.
All commits build.
