feat: M2 + M3 — AuthService, MLS group lifecycle, Delivery Service
M2:
- schemas/auth.capnp: AuthenticationService (upload/fetch KeyPackage)
- noiseml-core: IdentityKeypair (Ed25519), generate_key_package, NoiseTransport
with send_envelope/recv_envelope, Noise_XX handshake (initiator + responder)
- noiseml-proto: auth_capnp module, ParsedEnvelope helpers
- noiseml-server: AuthServiceImpl backed by DashMap queue (single-use KPs)
- noiseml-client: register + fetch-key subcommands, ping over Noise_XX
- tests: auth_service integration test (upload → fetch round-trip)
M3:
- schemas/delivery.capnp: DeliveryService (enqueue/fetch opaque payloads)
- noiseml-core/group.rs: GroupMember — MLS group lifecycle
create_group, add_member (→ Commit+Welcome), join_group, send_message,
receive_message; uses openmls 0.5 public API (extract() not into_welcome,
KeyPackageIn::validate() not From<KeyPackageIn>)
- noiseml-server: DeliveryServiceImpl on port 7001 alongside AS on 7000
- noiseml-proto: delivery_capnp module
TODO (see M3_STATUS.md):
- noiseml-client: group subcommands (create-group, invite, join, send, recv)
- noiseml-client/tests/mls_group.rs: full MLS round-trip integration test
