* Align XML parsing and libraries with Python 3.15
Retain the existing XML backend accounting changes and their explicit registry publication limitation. Preserve canonical XML tests and existing RustPython guards, including multiline marker explanations through update_lib.

* Retire proven XML guards and sync canonical consumers

* Rebase vendored xml onto 1.4.0
Replace the vendored crate sources with the published xml 1.4.0 archive
and reapply the amplification accounting patch on top of it. The two
lexer hunks that conflicted with the new line-ending normalization are
merged into the 1.4.0 read loop. The patch no longer normalizes CR in
entity values or collapses CRLF in attribute values, because the 1.4.0
lexer and attribute reader already do so.
Update the checksums, recorded upstream commit, archive hash and
provenance notes, and require version 1.4 for the path dependency.

* Remove stale SAX external resolver expected failure
Linux and macOS canonical CI both demonstrate that the existing
unsupported-scheme resolver test passes. Retire only its expected-failure
decorator through update_lib, preserving its canonical assertions.
This does not implement external DTD parsing.
AI assistance: dot diagnosed CI, migrated the marker, and reviewed the
source delta and normal-hook validation; the model version is not exposed.

* Support frozen ElementTree attribute mappings
Preserve assigned mapping identity while copying constructor attributes, and use checked union ownership through Element operations.

* Sync final ElementTree runtime and companion tests
Import ElementTree.py from CPython d220409a13b77de7a6c30abe16ea90db01528edc through update_lib migrate. Copy six complete canonical tests with update_lib copy-test, preserving all surrounding test markers. This aligns pure-Python and native frozendict diagnostic expectations and covers the runtime import companion changes.
