F8 cross-bank const-prop: bank-blind interior veto + unexported overlay targets (Asteroids DISPATCH-MISS 0x10C0)

Two compounding lift bugs kept Asteroids' kernel dispatch destinations unrooted. (A) _detect_zp_indirect_jmp_constprop Phase 3 built its misalignment veto from the MERGED instruction dict during the cross-bank overlay — bank-1 alias instructions at the same 13-bit window addresses vetoed clean bank-0 targets ($D0C0 masked 0x10C0 was "interior" of a bank-1 byte span; runtime exited at f=194 with DISPATCH-MISS target=0x10C0).
