/**
 * Persistence for ContentLibrary. Whole-library JSON snapshot (vs the
 * trade log's append-only JSONL) because content records are mutable
 * throughout their life — new drafts, new assets, status transitions —
 * so append-only would require replaying every edit on load. A single
 * re-written JSON file is simpler and content volume is orders of
 * magnitude smaller than a trade log.
 *
 * Disk failures and corruption are always survivable: save is
 * best-effort, load returns `null` on any error so the agent falls back
 * to a fresh in-memory library rather than refusing to start.
