/**
 * rNotes Automerge document schemas — Vault Browser.
 *
 * rNotes is now a vault sync + browse module for Obsidian/Logseq vaults.
 * Rich editing moved to rDocs.
 *
 * DocId format: {space}:rnotes:vaults:{vaultId}
 *
 * Storage model:
 * - Automerge stores metadata (title, tags, hash, sync status)
 * - ZIP vault files stored on disk at /data/files/uploads/vaults/
 * - Content served on demand from ZIP (not stored in CRDT)
