…o format This commit enhances the Gecko format reporter in the sampling profiler to include markers for GIL acquisition events. The implementation adds: - GIL contention tracking in pystate and ceval_gil - New marker types in the Gecko collector for GIL wait events - External inspection support for reading GIL state - Sample collection of GIL acquisition times and thread states - Comprehensive tests for marker export functionality The markers provide visibility into GIL contention patterns, showing when threads are waiting to acquire the GIL and how long they wait.
