Multi-Path ZP-Indirect JMP Const-Propagation

Concern: Iter 7's single-path const-prop walked backward from one JMP site in address order and took the first matching LDA #imm / STA $ZP pair. Iter 8 generalises: enumerate EVERY immediate LDA writer for $ZP and $ZP+1, cross-product the (lo, hi) sets, seed all targets that map to ROM addresses.

Raw traces, ROM material, local paths, and personal data are not part of this public record.
