First half of the browser-native bus SDK (issue 0001, Phase 1):
- crypto.ts: Ed25519 sign/verify (@noble), ChaCha20-Poly1305 AEAD (@noble),
endpoint id (sha256+base64url), and the anonymous sealed box for room-key
distribution. The sealed-box nonce is BLAKE2b-192 over ephPub||recipientPub,
matching Go's nacl/box.SealAnonymous (NOT SHA-512) so a Go-sealed key opens here.
- frame.ts: the Frame wire format, reproducing Go encoding/json byte-for-byte —
struct field order, omitempty rules, base64-std byte fields, and the default
HTML escaping (<, >, &, U+2028/U+2029) — plus sign/verify over canonical bytes.
vectors.test.ts checks all of it against the golden vectors generated by unibus
cmd/busvectors. 11/11 green: endpoint id, Ed25519 (incl. frame signature),
AEAD seal+open, sealed box open + round-trip, and frame signing-bytes + wire
marshal. This pins cross-language interop with Go/Kotlin peers.
Adds @noble/ciphers, tweetnacl (runtime) and vitest (dev).
