Add a `nativeThreadId` attribute to `LogRecord` that exposes theOS-native thread ID via `threading.get_native_id()`. This is usefulfor correlating log entries with system tools like htop, strace, andperf that display native thread IDs.The attribute can be used in format strings as `%(nativeThreadId)d`.Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
