/**
 * Compact before/after snapshots for steering ledger entries.
 *
 * Ledger entries used to embed the FULL plan (every goal, criterion, and
 * evidence string) twice per audit and twice more at the entry top level.
 * That made each accepted steer O(plan size) on disk, so the ledger grew
 * quadratically over a run, and every dedup scan re-hydrated all of it into
 * memory. A snapshot instead records plan-level counters plus only the goals
 * the mutation actually touched, keeping each entry O(changed goals).
