• [ET][native] Verify bundled LLM samples through the runner #24175
• [ET][native] Bundle LLM prefill and decode samples from export_hf_llm #24174
• -> [ET][native] Read bundled samples in C++ #24173
• [ET][native] Make the LLM runner's next-token choice pluggable #24172
• [ET][native] Bundle sample method calls in .ptn packages #24171

Adds read_sample_set, which reads one samples/<method>/<set>/ from a
.ptn into calls with resolved tolerance. It validates like read_samples
and rejects scalar and list values.
