Hojun-Cho fe32dedb08 lib/ww/lex: char-literals for lexer magic decimals (Wave-1) ...

Pure byte-id-neutral substitution of ASCII magic decimals with char
literals across lex.ww (131) + tok.ww (19); regen w6c + wwdump
combined.ww (lex is embedded in those two only).

escape() out-values for \a (7) and \b (8) are now '\a'/'\b' — both
the C bootstrap lexer (cmd/wcc/lex.c:160-161) and ww's own escape()
map them, so the literals are value-equivalent and stage-symmetric.

Digit-value arithmetic (parseint/parsef64/hexchar: c - '0' over u8)
is left decimal: a rune/i32 char literal would promote the u8 operand
and is not byte-id-neutral. Multi-byte type-suffix comments (i8../f64)
are kept — they label more than a single char.
