# Build + RUN the M8 HNSW vector-index tests. Pure C11 (gcc/cc), stdlib + libm
# only. This is a standalone C module — NOT folded through elb/elc.
#
# Two passes:
#   1. PERF  — optimised (-O2, no sanitizer): the real recall@10 gate + speedup
#              numbers at full size (N=5000 recall, N=5000/20000 speedup).
#   2. SAFETY — ASan + UBSan on the same suite at reduced size (VINDEX_QUICK=1);
#              memory-safety is size-independent, so this stays fast.
