internal/storage/ provides: - Open(path) to create or open the SQLite database with WAL journal, busy timeout, and foreign keys enabled - Embedded migrations that create the users table on first run - UserStore with Create, GetByID, GetByEmail, UpdateLastLogin, Delete - Email normalisation (trim+lowercase) and uniqueness enforcement with ErrEmailTaken - ErrNotFound on lookups and deletes - UUIDv4 IDs auto-generated when caller leaves ID empty Uses modernc.org/sqlite (pure-Go) so the binary stays CGO-free and matches Dockerfile.dev's CGO_ENABLED=0. Tests cover all CRUD operations, email uniqueness (case-insensitive), WAL mode verification, and ErrNotFound paths. Closes #8. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
