* feat(common): add Double Ratchet algorithm — 6.1Christophe Besson2026-08-091-0/+311
| | | | | | | | | | | | | | | | | RatchetState: full Signal-spec Double Ratchet (DH ratchet + symmetric ratchet). KDF_RK/KDF_CK via HKDF-SHA256. AES-256-GCM message encryption. MKSKIP for out-of-order delivery (max 1000 skipped keys). ChatMessage dataclass with to_dict/from_dict for wire serialisation. Properties validated by tests: ✓ Forward secrecy (consumed keys unreplayable) ✓ Out-of-order delivery ✓ Associated data binding ✓ Break-in recovery (post-ratchet keys independent) ✓ 100-message stress test 11/11 tests in 0.06s.

* chore: initialize monorepo structure for MeshBayChristophe Besson2026-08-093-0/+247
3-package layout: meshbay-common (shared crypto/protocol), meshbay-hub (FastAPI server), meshbay-node (local daemon). Includes validated POC spikes 1-6 in poc/, architecture drafts v1/v2 in docs/, and CLAUDE.md project conventions. All cryptographic primitives extracted from POC into meshbay_common/crypto.py (GEK wrap/unwrap, chunk key derivation, keystore encryption, chunk signing).
