Const-Prop Interior-Address Filter — Partial Misalignment Suppression

Concern: Iter 11 surfaced a misalignment cascade in bank-0 virtual address space: bank-0's sub_011B00 decoded a stray 0x02 JAM at $11B13 (mid-instruction of the STA $02 at bank-0 $1B12), and platform_exit(cpu) for that JAM is now Asteroids' visible exit point. Iter 12 attacks the cascade at its source: the multi-path const-prop's (lo × hi) cross-product over-seeds — for Asteroids' bank-0 walk, the const-prop discovers candidate targets like…
