Phase 1: Compatibility skeleton complete. Native-Rust forensic reimplementation of libxml2+libxslt with C ABI drop-in replacement. 62 tests passing, ABI courts verified, C headers compatible, Docker oracle built.

//!//! libxml2's own URI parser implementation. NOT a general URI library —
//! parity of malformed-URI handling is UPSTREAM_QUIRK territory.
//!//! Phase 0: scaffolded. Implementation begins in Phase 4.
