/**
 * OfflineStore — filesystem-based governance state store.
 *
 * Mirrors the engine's storage layout under `.forgeos/state/`:
 *
 *   .forgeos/state/
 *     pipelines/     {changeset_id}.json
 *     evidence/      {changeset_id}/{gate_id}.jsonl
 *     reviews/       {changeset_id}.json
 *     initiatives/   {initiative_id}.json
 *
 * All JSON writes are atomic (write to .tmp, rename). Evidence uses
 * JSONL append for efficient incremental writes.
 *
 * Uses only Node.js built-ins (fs, path, crypto). No external dependencies.
