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.

Number interface methods in source order and check each class against every
implemented interface, reporting missing, private, mismatched, conflicting,
and non-interface implementations at the class declaration.
