CI Visibility: Fixes an issue where HTTP 429 (Too Many Requests) responses from the Datadog backend were treated as non-retriable errors, causing CI visibility data to be dropped when the backend applied rate limiting. The backend connector now retries on 429 responses and respects the X-RateLimit-Reset header when present to determine the retry delay.
internal: A bug preventing certain periodic threads of ddtrace (like the profile uploader) from triggering in fork-heavy applications has been fixed.
profiling: Fixes an issue where setting an unlimited stack size (ulimit -s unlimited) on Linux caused the stack profiler sampling thread to fail to start, resulting in empty CPU and wall-time profiles. #17132
