a298c9430c TUI chat interface with real-time E2E encrypted messaging 
`warzone chat [peer-fp] -s <server>` launches an interactive terminal UI:
- Header: your fingerprint, peer fingerprint, server URL
- Message area: color-coded (green=you, yellow=peer, cyan=system)
- Input bar with cursor at bottom
- Background polling every 2s for incoming messages
- Full X3DH + Double Ratchet on send/receive
- Session persistence across messages

Commands in TUI:
- /peer <fingerprint> — set who you're chatting with
- /info — show your fingerprint
- /quit or /q or Esc or Ctrl+C — exit

Usage:
  warzone chat "6baf:6d0b:4541:9cae:f06b:83da:69bc:05ee" -s http://localhost:7700

8dd45b1bfe Normalize fingerprints everywhere: strip colons from URLs and DB keys 
Client: strip colons before putting fingerprints in URL paths
(colons in URLs confuse axum path matching).

Server: normalize fingerprints in message routes too.

All fingerprint storage and lookup is now hex-only, case-insensitive.

de118371de Fix bundle lookup: normalize fingerprints, handle 404 gracefully 
Server: normalize fingerprints by stripping colons and lowercasing
before storing/looking up in sled. Adds tracing for register/lookup.

Client: check HTTP status before parsing JSON response body.
Shows clear error when user is not registered instead of parse error.

722441c391 Add WARZONE_HOME env var for separate user data directories 
All data paths now use keystore::data_dir() which checks
WARZONE_HOME first, falls back to ~/.warzone.

This avoids the HOME override hack that breaks rustup/cargo.

Usage: WARZONE_HOME=/tmp/bob warzone init

94b845eb5b Fix all compiler warnings across server and client 
- Remove unused ServerConfig struct (config via CLI args)
- Remove unused otpks field from Database (not yet needed)
- Wire AppError into message routes with proper error propagation
- Remove unused imports in send.rs (Seed, MessageContent, etc.)
- Suppress dead_code on BundleResponse.fingerprint (needed by serde)

Zero warnings, 17/17 tests pass.

82f5061aa1 Wire E2E messaging: send, recv, session persistence, auto-registration 
CLI client (warzone):
- `warzone init` now generates pre-key bundle (1 SPK + 10 OTPKs),
  stores secrets in local sled DB, saves bundle for server registration
- `warzone register -s <url>` registers bundle with server
- `warzone send <fp> <msg> -s <url>` full E2E flow:
  - Auto-registers bundle on first use
  - Fetches recipient's pre-key bundle
  - Performs X3DH key exchange (first message) or uses existing session
  - Encrypts with Double Ratchet
  - Sends WireMessage envelope to server
- `warzone recv -s <url>` polls and decrypts:
  - Handles KeyExchange messages (X3DH respond + ratchet init as Bob)
  - Handles Message (decrypt with existing ratchet session)
  - Saves session state after each decrypt

Wire protocol (WireMessage enum):
- KeyExchange variant: sender identity, ephemeral key, OTPK id, ratchet msg
- Message variant: sender fingerprint + ratchet message

Session persistence:
- Ratchet state serialized with bincode, stored in sled (~/.warzone/db)
- Pre-key secrets stored in sled, OTPKs consumed on use
- Sessions keyed by peer fingerprint

Networking (net.rs):
- register_bundle, fetch_bundle, send_message, poll_messages
- JSON API over HTTP, bundles serialized with bincode + base64

651396fa13 Scaffold Rust workspace: warzone-protocol, server, client, mule 
4 crates, all compile. 16/17 tests pass.

warzone-protocol (core crypto):
- Seed-based identity (Ed25519 + X25519 from 32-byte seed via HKDF)
- BIP39 mnemonic encode/decode (24 words)
- Fingerprint type (SHA-256 truncated, displayed as xxxx:xxxx:xxxx:xxxx)
- ChaCha20-Poly1305 AEAD encrypt/decrypt with random nonce
- HKDF-SHA256 key derivation
- Pre-key bundle generation with Ed25519 signatures
- X3DH key exchange (simplified, needs X25519 identity key in bundle)
- Double Ratchet: full implementation with DH ratchet, chain ratchet,
  out-of-order message handling via skipped keys cache
- Message format (WarzoneMessage envelope + RatchetHeader)
- Session type with ratchet state
- Storage trait definitions (PreKeyStore, SessionStore, MessageQueue)

warzone-server (axum):
- sled database (keys, messages, one-time pre-keys)
- Routes: /v1/health, /v1/keys/register, /v1/keys/{fp},
  /v1/messages/send, /v1/messages/poll/{fp}, /v1/messages/{id}/ack

warzone-client (CLI):
- `warzone init` — generate seed, show mnemonic, save to ~/.warzone/
- `warzone recover <words>` — restore from mnemonic
- `warzone info` — show fingerprint and keys
- Seed storage at ~/.warzone/identity.seed (600 perms)
- Stubs for send, recv, chat commands

warzone-mule: Phase 4 placeholder

Known issue: X3DH test fails (initiate/respond use different DH ops
due to missing X25519 identity key in bundle). Fix in next step.
