Initial 68020+ full-format indexed JSR support in reference interpreter for no-memory-indirect addressing, optional base/index suppression, scaled index and word/long base displacement. Reject unsupported memory-indirect formats. Add 128-step reference/optimized CPU+RAM differential for full extension with word base displacement and suppressed index. Await CI; this is not complete 68020 addressing coverage.
