Check Script read names with Rust's alphabetic and alphanumeric tests, so it split names at U+2118, U+203F, U+00B7 and the zero width non-joiner and joiner, and took U+00B2 and U+2E2F into names. It now uses the Unicode 16.0 ID_Start and ID_Continue rule that vectorcraft-js uses, with `$` and `_` (https://www.unicode.org/reports/tr31/, https://tc39.es/ecma262/#sec-names-and-keywords). A `\uXXXX` escape is part of a name only when it stands for a character the name may hold where it is: `\u0030abc` no longer becomes `0abc`, and malformed escapes end the name. The engine's lexer comparison test now checks that both crates take the same characters into names, written out and as escapes.
