WASM fix (critical):
- encrypt_key_exchange_with_id was calling x3dh::initiate a second time,
generating a new ephemeral key that didn't match the ratchet — receiver
always failed to decrypt. Now stores X3DH result from initiate() and
reuses it. Added 2 protocol tests confirming the fix + the bug.
- Bumped service worker cache to wz-v2 to force browsers to re-fetch.
- Disabled wasm-opt for Hetzner builds (libc compat issue).
Federation — alias support:
- resolve_alias falls back to federation peer if not found locally
- register_alias checks peer server before allowing — globally unique aliases
- Added resolve_remote_alias() and is_alias_taken_remote() to FederationHandle
Federation — key proxy fix:
- Remote bundles no longer cached locally (stale cache caused decrypt failures)
- Local vs remote determined by device: prefix in keys DB
Client fixes:
- Self-messaging blocked ("Cannot send messages to yourself")
- /peer <self> blocked
- last_dm_peer never set to self
- /r <message> sends reply inline (switches peer + sends in one command)
Deploy tooling:
- scripts/build-linux.sh with --ship (build + deploy + destroy)
- --update-all, --status, --logs commands
- WASM rebuilt on Hetzner VM before server binary
- deploy/ directory: systemd service, federation configs, setup script
- Journald log cap (50MB, 7-day retention)

Server:
- Register stores per-device bundles: device:<fp>:<device_id>
- GET /v1/keys/:fp/devices lists all registered devices
- WS already pushes to ALL connected devices per fingerprint
- DB queue: first device to poll gets messages (acceptable for Phase 2)
Multi-device flow:
- Same seed on two devices → same fingerprint
- Both register with different device_ids
- Both connect via WS → both receive messages in real-time
- Each device maintains its own ratchet sessions

Axum 0.7 uses :param for path parameters. {param} is axum 0.8+ syntax.
Routes were silently not matching, causing 404 on all key lookups.

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.
