This commit adds a new OpenTelemetry interceptor (opentelemetryv2) with enhanced capabilities for Temporal workflow integration: Features: - Deterministic ID generation for spans/traces in workflows using TemporalIdGenerator - Context propagation across workflow and activity boundaries - Support for workflow-level span creation via workflow.start_as_current_span - Enhanced interceptor with context propagation to activities and nexus operations - Compatible with existing opentelemetry module while providing additional functionality Implementation: - New TemporalIdGenerator uses workflow.random() for deterministic IDs in workflows - TracingInterceptor handles client, worker, activity, workflow, and nexus operations - Workflow-safe span creation context manager in workflow module - Comprehensive test coverage for trace propagation scenarios This is separate from the OpenAI agents OTEL integration and provides general-purpose OpenTelemetry improvements for Temporal workflows. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
…inting fixes This commit significantly improves the OpenTelemetry v2 integration for the Temporal SDK with the following enhancements: ## Core Features Added: - **Comprehensive test coverage**: Added `test_opentelemetryv2_comprehensive_tracing` covering all workflow operations including activities, local activities, child workflows, timers, signals, updates, queries, and Nexus operations - **Read-only mode detection**: Implemented `workflow.unsafe.is_read_only()` to prevent span ID generation errors during queries and update validators - **Test isolation**: Added pytest fixture to reset OpenTelemetry tracer provider state between test runs - **Span hierarchy validation**: Refactored tests to use `dump_spans()` hierarchy validation for better maintainability ## Linting and Documentation: - Fixed all import path issues for OpenTelemetry ID generators - Added comprehensive docstrings for all public classes and methods - Fixed type annotations and null handling throughout the codebase - Resolved Nexus headers access issues with proper type protocols - Achieved complete pydocstyle compliance ## Technical Improvements: - Enhanced `TemporalSpanProcessor` with proper replay handling - Improved `TemporalIdGenerator` with deterministic workflow-safe random generation - Updated span parenting validation to ensure proper trace relationships - Added max_cached_workflows=0 to all test workers for deterministic behavior 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Summary
This PR introduces a new OpenTelemetry v2 integration for the Temporal Python SDK with significant enhancements over the existing OpenTelemetry support. The integration provides deterministic tracing, comprehensive test coverage, and improved maintainability.
Key Features Added:
