the issue right now is the interaction between FunctionDispatcher and ClusterShuffle specifically. FunctionDispatcher creates blocks with raw PUSH imm. (BlockControl::Unknown/Terminal), not symbolic JumpTarget::Block targets. so when ClusterShuffle moves blocks afterward, those raw PUSH values become stale. the entire patch re-application machinery (dispatcher patches, stub patches, decoy patches, controller patches, min_push_width, remap_metadata_pcs, pre_reindex_pc_mapping composition) exists to fix up those stale values and it's still producing ~21-25 invalid jump targets.

but what if ClusterShuffle runs first, FunctionDispatcher writes its raw PUSH values against the already-shuffled layout, and they're correct from the start. no re-application needed. attempting this approach
