* Security: Further harden XML injection prevention during unparse (follow-up to
v0.15.0). In addition to '<'/'>' rejection, now also reject element and
attribute names (including `xmlns` prefixes) that:
- start with '?' or '!'
- contain '/' or any whitespace
- contain quotes (' or ") or '='
- are non-strings (names must be `str`; no coercion)

* Security: Prevent XML injection (CVE-2025-9375) by rejecting '<'/'>' in
element and attribute names (including `xmlns` prefixes) during unparse.
This limits validation to avoiding tag-context escapes; attribute values
continue to be escaped by the SAX `XMLGenerator`.
