Fix X3DH + add web client served by warzone-server
X3DH fix: - Added identity_encryption_key (X25519) to PreKeyBundle - initiate() and respond() now use correct DH operations per Signal spec: DH1=IK_a*SPK_b, DH2=EK_a*IK_b, DH3=EK_a*SPK_b, DH4=EK_a*OPK_b - All 17 tests pass including x3dh_shared_secret_matches Web client (served at /): - Identity generation with seed (stored in localStorage) - Recovery from hex-encoded seed - Auto-load saved identity on page load - Fingerprint display (same format as CLI: xxxx:xxxx:xxxx:xxxx) - Key registration with server via /v1/keys/register - Chat UI with message polling (5s interval) - Commands: /help, /info, /seed - Dark theme matching warzone aesthetic Both clients (CLI + Web) now exist: - CLI: warzone init, warzone info, warzone recover - Web: http://localhost:7700/ (served by warzone-server) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
