feat: Phase 6 complete — chat, multi-group, federation, replication, webcrypto
6.1 Double Ratchet (meshbay_common/ratchet.py):
Forward secrecy, break-in recovery, out-of-order delivery.
Signal-spec KDF_RK/KDF_CK via HKDF-SHA256. 11/11 tests.
6.2 Multi-group node (config.py):
[[groups]] TOML array, per-group ports, back-compat [group].
6.3 MHP federation persistence (db/models.py FederatedGroup + SwarmSource):
receive_directory() now persists to federated_groups table.
list_public_groups() includes federated results with source attribution.
6.4 Content replication (node/replication.py + hub SwarmSource):
ContentReplicator: fetch-index, download, hash-verify, register-swarm.
Hub: POST /v1/swarm/register, GET /v1/swarm/{hash} for multi-source.
6.5 Browser private group (webcrypto.py + static/crypto.js):
AES-256-GCM variant of GEK for WebCrypto-compatible groups.
crypto.js: SubtleCrypto importGEK + deriveChunkKey + decryptChunk.
Keys distinct from ChaCha20 via :aes HKDF info suffix. 4/4 tests.
74/74 tests total.
