webtecnica 815934ae52 fix(cron): scheduler self-heals after EMFILE instead of stalling silently (#87644)
tick() swallowed a real OSError at tick-lock acquisition as 'another
instance holds the lock', so fd exhaustion (EMFILE/ENFILE) made the
scheduler return 0 — recorded as a successful tick — while no job ever
ran again. Heartbeat and success markers stayed fresh, masking the stall.

- propagate lock-acquisition OSError to the ticker loop (records + backs off)
- detect fd exhaustion, attempt gc.collect() + raise soft nofile limit
- exponential backoff so an exhausted process stops hammering the store
- preserve genuine lock contention (EWOULDBLOCK) silent-skip behavior
- 11 regression tests
