libxml-rs 0.1.0-alpha.33

Native-Rust forensic reimplementation of libxml2+libxslt with C ABI drop-in replacement. Cross-version oracle matrix (libxml2 2.7.8-2.15.3, libxslt 1.1.26-1.1.45) with semantic epochs correlated to upstream commits; full xmllint/xmlcatalog/xsltproc CLIs; differential-court-verified C API closure (xmlXPath*, xmlTextReader*, xmlTextWriter*, catalogs, serialization, data globals, chvalid, encoding, the full libxslt surface) — parity ledger at 0 missing for both libxml2 and libxslt; residual closure loop (73 FIXED / 2 bounded obligations) sealed by differential court matrix; C14N, format-number(), number(), compile-time XSLT select/test validation, and undefined-prefix QName preservation verified byte-identical against libxml2 2.15.3 / libxslt 1.1.45 oracle. 1177 tests passing.
