Lua now joins tcl/ocaml/kernel/common-lisp in consuming lib/guest/lex.sx via
prefix-rename. Removes 28 lines of duplicated character-class helpers
(lua-make-token, lua-digit?, lua-hex-digit?, lua-letter?, lua-ident-start?,
lua-ident-char?, lua-ws?) and replaces with the 8-line prefix-rename block.
The byte-table additions from loops/lua (__ascii-tok, __lua-127-255-tok,
lua-byte-to-char) are preserved at the top of tokenizer.sx — those provide
Lua's 8-bit-clean string semantics on top of the shared lex layer.
test.sh updated to preload lib/guest/lex.sx + lib/guest/prefix.sx before
lua sources, matching the load order arch's pre-merge test.sh used.
393/395 maintained. The 2 pre-existing failures are unrelated:
- math.random(n) primitive arity issue
- os.clock returns rational instead of number (SX division semantics)
Skipped from the planned follow-up: delay/force port. Arch's lua-force was
defined but never referenced anywhere — dead code, not worth porting.
