scripts/benchmark.sh generates a deterministic corpus, builds PureXML
in release and a C driver against the SDK's libxml2, times parse,
serialize, and XPath over the same bytes (best-of-N, internal timing,
IO excluded), cross-checks the same XPath count on both sides, and
prints the comparison. First honest baseline recorded in
docs/benchmarks.md: parse ~30x, xpath ~36x, serialize ~5x slower than
libxml2 on a 4.2 MB corpus; these are the numbers #139's optimization
passes burn down. The SAX stage isolation is blocked on #142 (the
public streaming surface is internal, found by this harness).
