mtlcl410andClaude Opus 5.5 c405d280c6 M8: metadata check fails closed and finds letter-spaced and short XMP values (#2448) ...

Review follow-up on #2539:
- the glyph end includes character and word spacing, so letter-spaced
  redacted text is one word and still matches /Title (Bluefin);
- an XMP value wholly part of a removed run goes, as an /Info value does
  (J. Li), compared as whole words (True stays with "untrue");
- when the removed text was cut short (too many runs, a run too long, too
  many terms) every /Info string and XMP stream goes instead of searching
  what was kept;
- XMP that is not valid UTF-8 or UTF-16 (also UTF-16 without a leading
  mark) is not searched lossily but removed;
- namespace declarations and the xpacket wrapper are not searched;
  comments and other processing instructions are;
- the raw-byte assertion saves without object streams so it can see /Info.
