Greptile Summary

The release updates both packages to version 0.24.0 and improves trace continuity and per-step observability across ACP and Temporal boundaries.

• Continues inbound W3C trace context through ACP request handling and downstream Temporal dispatch.
• Adds per-step observability wrappers for business Temporal activities while retaining ambient-span handling for split tracing activities.
• Adds backend-drift diagnostics and focused tracing regression tests.
• Synchronizes package manifests, generated version metadata, statistics, and changelogs.

Confidence Score: 5/5

The PR appears safe to merge because no blocking failure remains within the scope of this follow-up review.

Important Files Changed

Filename	Overview
src/agentex/lib/sdk/fastacp/base/base_acp_server.py	Adds request-scoped W3C trace-context extraction and guaranteed context detachment around ACP HTTP handling.
src/agentex/lib/core/tracing/trace.py	Distinguishes split tracing-dispatch activities from business activities so only in-process business spans receive dedicated observability wrappers.
src/agentex/lib/core/tracing/obs_span.py	Adds OTel-first wrapper and ambient-tag behavior for Temporal execution, with fail-open backend fallback.
src/agentex/lib/core/tracing/obs_ids.py	Renames the OTel-selection option and adds deduplicated warnings when configured and active observability backends differ.
tests/test_temporal_obs_backend.py	Expands coverage for dispatch discrimination, business-activity wrappers, OTel correlation, and backend-drift diagnostics.
tests/test_trace_context_extraction.py	Covers inbound traceparent extraction, repeated tracestate headers, baggage exclusion, and safe context detachment.
