Migrate Reader relational persistence from Turso to project-owned Cloudflare D1 while preserving Better Auth, document ownership, annotations, and R2 behavior.
Acceptance:
- D1-backed Drizzle/Better Auth boundary and deterministic migrations
- isolated local development and targeted tests
- D1-aware env/deploy/operator paths
- sanitized parity receipt and rollback proof
- explicit approval before remote resource creation, production data operations, config mutation, or deploy
- Turso retirement remains separate
