What was changed

A [TMPRL1103] warning is logged when an outgoing gRPC request or a Workflow command carries payloads above the configured limit (512 KiB payloads, 2 KiB memo by default).

Why?

Closes #802.

Checklist

  • Covered by tests

Log a [TMPRL1103] warning when an outgoing gRPC request or a Workflow
command carries payloads above the configured limit.
RoadRunner already emits TMPRL1103 for the commands it sends: sdk-go installs
the payload limit visitor in NewAggregatedWorker with the same 512 KiB / 2 KiB
defaults. The PHP side was never wired into WorkerFactory, and wiring it would
convert every payload twice.
