Initial implementation on the suaveplan branch.

### Added

- `sodiumReady(): Promise<void>` — lazy WASM initialisation singleton.
- `sodiumAeadEngine` — XChaCha20-Poly1305 / ChaCha20-Poly1305 / AES-256-GCM AEAD engine.
- `sodiumAesGcmEngine` — AES-256-GCM–preferring AEAD engine (falls back to ChaCha20).
- `createSodiumAeadEngine(opts)` — factory for custom AEAD engine configurations.
- `sodiumSignEngine` — Ed25519 sign/verify/generateKeypair engine.
- `sodiumAgreeEngine` — X25519 Diffie-Hellman agree/generateKeypair engine.
- `sodiumSealedBoxEngine` — anonymous-sender sealed box (`crypto_box_seal`).
- `sodiumAuthBoxEngine` — authenticated box (`crypto_box_easy`).
- `cryptoKdf` — BLAKE2b-based deterministic subkey derivation.
- `cryptoAuth` / `cryptoAuthVerify` — BLAKE2b MAC.
- `cryptoPwhashStr` / `cryptoPwhashStrVerify` — Argon2id password hashing.
- `ristretto255` namespace — group operations (add, sub, mul, fromHash, toBytes, fromBytes, random).
- `SodiumError` + `SODIUM_CODES` — structured error surface.
