Preserve the existing terminal-tail recognizer and accept a contiguous
framed method-pointer thunk followed by its separate null-error call.
Reject stores that overwrite saved FP/LR, unproven store addresses and
stack/frame/link-register clobbers, including WSP. Stores are limited to
fixed caller stack-argument slots above the saved frame.
Keep the fallback narrower than #188's proposed unframed block recognition.
Add synthetic AArch64 regressions and document the rule beside the other
tail-call findings; no game-specific IDs, fixed addresses or profile changes.
Validation: 179 tool tests run, 174 passed and 5 skipped; 10 tail-call tests
pass; the legacy terminal recognizer is AST-identical to main; git diff
--check passes. Real game modules were not rewritten for this integration.
