fix(schema): resolve an unprefixed xsi:type in the instance namespace context (#383) 
An xsi:type value is a QName: a prefix binds through that prefix, an unprefixed
name through the in-scope default namespace, and with no default namespace an
unprefixed name is in no namespace. PureXML stores each named type under both its
namespaced key and a bare local-name alias (for lenient lookup), so an unprefixed
xsi:type="Test" matched a {targetNS}Test through the alias even when the instance
had no default namespace, wrongly typing an otherwise-undeclared root and
accepting the document (W3C XSTS targetNS00101m; libxml2 rejects it identically).

xsiTypeReference now keys an unprefixed xsi:type to the in-scope default namespace
(none here) rather than returning the bare local name, so xsi:type="Test" names
no-namespace Test, which does not exist; the root then has neither a declaration
nor a usable type and the instance is invalid. A prefixed xsi:type and an
unprefixed one under a default namespace equal to the target namespace are
unaffected, and the child-element builtin-substitution path keeps its bare-name
fallback (xsiTypeName), so an unprefixed builtin still substitutes where valid.

Verified over the full W3C XSTS corpus in release: invalid-instances-accepted
6 -> 5, valid-instances-rejected held at 0 across all 14383 groups, full suite
(1840 tests) and wasm green. An adversarial critic traced every resolveNamedType
branch, including the unprefixed-builtin-via-key case, and confirmed the only
path that no longer resolves corresponds to a spec-invalid reference, so no valid
instance is newly rejected.
