Reruns the ESP32-S3 suite on runtime 0.10.2, which no longer sleeps between stages on ESP-IDF, and pins each suite to the core that produced its own results.

• core-versions.json (format 2) pins compiler and runtime per suite. check_core_versions.py checks each suite's pins against that suite's summary and takes --suite for the checkout check, so a change that can only move one target's numbers reruns only that suite. The Cortex-M suite keeps its pins and results.
• Every ESP32-S3 TiGrIS capture now ends with a BENCH_PROVENANCE: line naming the compiler and runtime it was built from. The collector derives the summary's producing revisions from those lines, so the summary stays a byte-identical reconstruction of its captures.
