Replace hand-rolled polling loops, semaphores, and WaitGroups
in all 7 background workers with go.gearno.de/kit/worker. Each
worker now implements Handler[T] (Claim/Process) and optionally
StaleRecoverer, gaining automatic Prometheus metrics and
OpenTelemetry tracing. Bumps kit from v0.3.0 to v0.5.0.
