Adds pure crypto layer usable by both daemon and client for the ARC v3 E2E-encrypted relay flow (Phase 10 of the v3 daemon plan). - `packages/client/src/crypto.ts`: `generateKeypair`, `box`, `unbox` (returns null on auth failure), and URL-safe base64 helpers. Wraps `tweetnacl` for zero-native-build crypto_box (Curve25519 + XSalsa20 + Poly1305). - `packages/client/src/pairing.ts`: Zod schema + encode/decode for the compact QR pairing payload (v, relayUrl, daemonPub, pairCode, label). JSON is canonicalized before base64url so identical payloads always encode to the same string. - `tests/crypto-primitives.test.ts`: 15 vitest cases covering keypair shape, box/unbox roundtrips, tamper/wrong-key/wrong-nonce rejection, base64url safety, and pairing payload encode/decode including malformed inputs and schema violations. Primitives only — relay server and daemon pairing flow are follow-up batches.

Summary
packages/client/src/crypto.ts—generateKeypair,box,unbox(null on auth failure), and URL-safe base64 helpers, wrappingtweetnacl(zero native build, Curve25519 + XSalsa20 + Poly1305).packages/client/src/pairing.ts— Zod schema + canonical encode/decode for the compact QR pairing payload (v,relayUrl,daemonPub,pairCode, optionallabel).tests/crypto-primitives.test.ts— 15 vitest cases: keypair shape & uniqueness, box/unbox roundtrip, tamper/wrong-nonce/wrong-key rejection, base64url safety, pairing payload roundtrip + malformed-input errors + schema-version rejection.Context: Phase 10 of the ARC v3 daemon plan (E2E-encrypted relay). Primitives only — the relay server (Unit 10) and daemon pairing flow will consume these in follow-up batches.
