* feat: enforce max queue deliveries in handlers with graceful failure
Replace VQS maxDeliveries cap with handler-level enforcement. Handlers
now gracefully fail runs/steps after excessive queue redeliveries,
preventing "phantom stuck" runs.
- Add MAX_QUEUE_DELIVERIES constant (64) and enforce in both workflow
and step handlers with run_failed/step_failed events
- Remove maxDeliveries from VQS trigger configs (builders + sveltekit)
- Improve world-local queue: safety limit loop, structured logging
with runId/stepId, backoff delay on failures
- Add MAX_DELIVERIES_EXCEEDED error code

* address PR review comments
- Expand max-delivery comments explaining minimal-work approach
- Make workflow handler error message verbose (matching step handler)
- Fix comment: "consume the message silently"
- Reduce local queue safety limit from 1000 to 256

* change MAX_QUEUE_DELIVERIES to 48 and use 5s linear backoff locally
VQS uses linear 5s backoff for attempts 1-32, then exponential capped
at 2h. At 48 attempts total elapsed time is ~20h, safely under the
24h message visibility limit. Local world now uses 5s linear backoff
to approximate VQS timing.
