Bug Fixes

• CI Visibility: Fix an unhandled RuntimeError that occurred when the git binary was not available. Git metadata upload is now skipped gracefully with a warning instead of aborting pytest startup.

• 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.

• Fixed an issue with internal periodic threads that could have caused a crash during shutdown if a fork occurred.

• Fix for a potential race condition affecting internal periodic worker threads that could have caused a RuntimeError during forks.

• 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.
