internal/auth/ provides:
- TokenStore: 32-byte cryptographically random one-time tokens.
Only the SHA-256 hash is persisted (so a DB leak doesn't grant
active sessions). Comparison uses subtle.ConstantTimeCompare.
Single-use is enforced via UPDATE ... WHERE used_at IS NULL.
- Signer: HS256 JWTs with 24h lifetime, jwt.WithValidMethods to
reject alg=none and other downgrade attacks.
- LogMailer (dev) and SMTPMailer (prod via net/smtp) behind a
Mailer interface.
- RateLimiter: DB-backed fixed window per email; default 5 per
15 min for the magic-link flow.
- Service: orchestrates RequestLogin (auto-creates user on first
login, generates token, emails magic link) and Verify (consumes
token, updates last_login, issues JWT).
- Handlers: POST /auth/login and GET/POST /auth/verify.
HandleLogin returns 202 even on validation failure to avoid
account enumeration; rate-limit hits surface as 429.
Schema additions: magic_tokens (with FK + cascade) and
login_attempts. UserStore.SetStoragePath added for completeness.
Tests cover: token issue/consume, single-use, expiry, rate limit,
JWT round-trip, alg=none rejection, signature tampering, purge,
HTTP handlers (login + verify, missing/invalid token paths).
Closes#9.

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.

Initial fork of github.com/alonswartz/notesium into librenotes:
- Source moved to internal/notesium/ (package notesium)
- Thin entry point at cmd/librenotes/main.go
- Module renamed to git.librete.ch/public/librenotes
- main() exposed as notesium.Run()
- LICENSE preserved (MIT), NOTICE added with attribution
- Web assets and completion.bash co-located with embedding code
to satisfy go:embed path constraints
Closes#3, #34, #35.
