/**
 * Persists the in-memory manifest state to disk.
 *
 * PERFORMANCE & SAFETY NOTES:
 * 1. Atomic Writes: We write to `.compound-sync/manifest.json.tmp` first,
 *    then use `fs.renameSync` to overwrite the actual manifest. This ensures
 *    that if the daemon crashes mid-write, we do not corrupt the JSON.
 * 2. Unsorted Keys: We do not sort the object keys before calling
 *    `JSON.stringify()`. Sorting requires significant CPU overhead for large
 *    workspaces. The in-memory object map is the source of truth; disk
 *    order does not matter.
 * 3. Synchronous I/O: All disk operations use `*Sync` APIs. A flush blocks
 *    the Node event loop briefly; see docs/features/sync/sync-manifest-design.md.
