it_find selects the table a class emitted for an interface, refusing a pair the
class does not implement, and if_assign, if_arg_push, if_elem_store, and
if_elem_load give assignment, argument passing, field, and array storage one
API that keeps all four value bytes. Two x128 fixtures prove the class and null
conversions, verbatim copies, array stride, argument layout, and the result
area, while the semantic suite still rejects an invalid conversion.

Classes now build one table per implemented interface, in implements order with
one two-byte entry per interface slot, and a failed class rolls back so a
missing method address is refused instead of dispatching to zero. The MAP gains
one TABLE record per table, and the x128 fixture checks table contents, distinct
per-class tables, both rollback paths, and the exact MAP text.

Generated programs now have control-flow emission, text and fault output, a
free-list heap, class descriptors, and object construction/deletion. Each
story lands with an x128 fixture and verifier so the runtime stays proven
before the parser drives code generation.
