ldm0 7f08c25f08 fix(dom): preserve template document identity and adoption lifecycles ...

Share a lazy inert owner across each document's template contents and keep
HTML/XML semantics, interface identity, and template-owner state separate.
Cloning preserves interfaces while creating independent owner state.

Separate portable Document metadata from arena-local relationships. Use
one metadata-copy boundary for Document cloning and main-document
replacement, clearing template-owner and CSS-target handles while keeping
whole-DOM snapshots and copy-on-write storage relationships intact. Metadata
copies also discard base-element href/target caches while retaining about
base URLs and explicit overrides; only DOM node cloning freezes computed
base URLs. Detached Document URL readers use native metadata without JS
URL/documentURI/baseURI shadow state, including selector and bridge readers.

Apply the DOM-specific document cloning rules separately: freeze the source
computed base URL as an override, separately retain the inherited about
base URL, and rebuild base-element caches from the cloned tree. Preserve
main-document replacement metadata semantics.

Establish exact HTML template identity and associated fragment allocation
in one native entry shared by DOM and parser creation. Clone actual native
contents rather than guessing from names, preserving foreign and mixed-case
elements through serialization, deep cloning, import and adoption. Keep HTML
createElement normalization at its binding boundary; namespace-aware creation
and wrapper selection preserve the exact local name, including registry paths.

Plan per-node adoption targets across ordinary children, shadow roots and
template contents. Retarget custom-element registries and callbacks with
the actual destination documents, and clear cross-document shadow sheets
while retaining sheets within a document and its own template owner.
Avoid preparing unused inert style sources.

Cover cross-arena ID collisions, metadata preservation, snapshot isolation,
nested templates, deep adoption, iframe/detached documents, cloned
interfaces, retained sheet arrays, registry associations and URL behavior.
