Subject: [PATCH 01/12] Report rescued recurring enqueue errors to Rails.error

RecurringTask#enqueue was swallowing Job::EnqueueError (and other-adapter
enqueue failures) without calling Rails.error.report, so production
outages like a read-only primary during failover only produced log lines
and missed Sentry Issues. Align with the gem's on_thread_error default.

Fixes #746

 termination

The forked lifecycle test already waits up to shutdown_timeout for the
supervisor PID to exit after repeated TERM signals. The async counterpart
only slept for 1s, which is flaky under load (e.g. Ruby 4 + rails_main + MySQL).

wait_for_jobs_to_finish_for waits on finished_at, which failed jobs never

Subject: [PATCH 04/12] Give concurrency controls tests more timing headroom on
 CI

Setup only waited 0.5s for processes to register, and a few scenarios used
tight pause windows that flake under MySQL CI load. Widen registration and
job-completion waits, and leave more margin so C still finishes last in the
throttled sequence test.

Subject: [PATCH 06/12] Isolate concurrency tests from recycled JobResult

Forked StoreResultJob workers from earlier tests can still write after
teardown and overwrite a JobResult whose id was reused, turning status
into "completed". Clear processes/records before creating @result, wait
for claimed slots before enqueueing blocked jobs, and tighten discard
setup timing.
