orbok-db

The authoritative orbok SQLite catalog (RFC-002): connection management, append-only migrations, and the repository layer.

Design rules implemented here:

• the catalog is authoritative; localcache payloads are elsewhere (Appendix A §3, separate orbok-cache.sqlite3);
• SQL stays inside repositories — application code sees typed records (RFC-002 §8);
• cleanup is executed only from a validated [orbok_core::CleanupPlan] (RFC-001 §14).
