Daniel Covington 26422557ac Add the scalar instruction emitter (E04-S03). Emit bounded documented instructions for scalar assignments, word and integer arithmetic, comparisons, and short-circuit booleans, with checked forward branch fixups. Add multiply and signed/unsigned divide helpers with a stable divide-by-zero result, plus a reviewed golden byte stream and disassembly.
