Unicode Set version 1.8.0

Enhancements

• Requires unicode ~> 2.1, bringing the Unicode 18.0 repertoire — the Jurchen, Proto_Cuneiform and Seal scripts, seven new blocks and ten Crown_* joining groups. Elixir 1.17 or later is now required.

• The Script_Extensions (scx), Age and Numeric_Type properties now resolve, so \p{scx=Latin}, \p{age=1.1} and \p{nt=decimal} match, backed by the new modules in unicode 2.1.

• \N{...} now resolves algorithmically-named characters — CJK and Tangut ideographs, Hangul syllables, and the Seal and Jurchen characters.

• \p{gc=LC} (Cased_Letter) now resolves through unicode's derived LC category, so the local workaround was removed.

• Resolve binary properties written with an explicit boolean value, so [\p{Extended_Pictographic=True}] matches the bare [\p{Extended_Pictographic}] and a false value selects the complement.
