Bug Fixes

• CI Visibility: Fixes an issue where pytest plugins pytest-rerunfailures and flaky were silently overridden by the ddtrace plugin. With this change, external rerun plugins will now drive retries as expected when Auto Test Retries and Early Flake Detection features are both disabled, otherwise our retry mechanism takes precedence and a warning is emitted.

• CI Visibility (pytest): Fixed missing ITR tags in the new pytest plugin that caused time saved by Test Impact Analysis to not appear in dashboards.

• CI Visibility: Fixed an issue where a test marked as both quarantined and attempt-to-fix was incorrectly treated as plain quarantined, preventing attempt-to-fix flow from running.

• LLM Observability: Fixes an issue where Anthropic LLM spans were dropped when streaming responses from Anthropic beta API features with tool use, such as tool_search_tool_regex.

• tracing: Resolves an issue where a RuntimeError could be raised when iterating over the context._meta dictionary while creating spans or generating distributed traces.

• Fix for potential crashes at process shutdown due to incorrect detection of the VM finalization state when stopping periodic worker threads.

• profiling: Fix potential reentrant crashes in the memory profiler by avoiding object allocations and frees during stack unwinding inside the allocator hook.

• profiling: the memory profiler now uses the weighted allocation size in heap live size, fixing a bug where the reported heap live size was much lower than it really was.
