w6a,w6l: char-literals for ELF/archive magic bytes (Wave-1)

Browse Source 
byte-id-neutral: every magic-decimal sub is value-equivalent to its
ASCII char-literal. 0x7F (ELF byte-0), ELFCLASS64=2, NUL sentinels,
and hex/itoa radix arithmetic kept decimal (no char identity).
Regenerated w6a/w6l main.combined.ww (the only two embedders).
