Update dev server to Server 1.32

[tconley1428]

What was changed

• Update the shared dev server to Server 1.32.
• Recognize payload-free Temporal system envelopes, including SignalWithStartWorkflowExecutionResponse.
• Report unsupported Temporal system payloads as retryable ApplicationErrors with the protobuf type in the message.

Why?

Server 1.32 can return a payload-free SignalWithStartWorkflowExecutionResponse. Supporting that known envelope avoids an unhelpful unknown-root failure, while unsupported system payloads now provide a clear compatibility diagnostic.

Validation

• poe lint
• poe test -s tests/worker/test_visitor.py -k "system_nexus_envelope or unknown_system_nexus_payload"
