Connects to a relay over QUIC with SNI "version", reads build hash
from a unidirectional stream, prints "<relay> <git-hash>" and exits.
Usage: wzp-client --version-check 172.16.81.175:4434
Output: 172.16.81.175:4434 8dbda3e
Relay side: detects "version" SNI, opens uni stream, writes
BUILD_GIT_HASH, waits 100ms for client to read, closes.

1. CLI client now sends raw room names (no hash), matching Android
JNI and Desktop Tauri. All three clients are now consistent.
2. When a client joins a global room, the relay merges federated
remote participants into the initial RoomUpdate. Previously,
clients that joined after the GlobalRoomActive signal only saw
local participants. Now they see everyone immediately.
3. Added get_remote_participants() to FederationManager for querying
cached remote participants from all peer links.

- Add SettingsScreen with identity (alias, key backup/restore), audio defaults,
server management, network prefs, and default room
- SettingsRepository persists all settings via SharedPreferences
- Auto-generate random display names on first launch (e.g. "Swift Wolf")
- Thread alias through CallOffer → relay handshake → RoomUpdate broadcast
- Derive caller fingerprint from identity key in relay handshake (fixes null
fingerprints when --auth-url is not set)
- Persist identity seed for stable fingerprints across reconnects
- Add alias field to SignalMessage::CallOffer (serde default for backward compat)

Client: sends SignalMessage::Hangup(Normal) before closing in all modes
(send-tone, file mode, silence mode) so the relay knows the session ended.
Relay: downgrades "timed out" / "reset" / "closed" recv errors from
ERROR to INFO since these are normal disconnect scenarios.

- Prefix unused _metrics_file in CliArgs
- Prefix unused _addr in Participant
- Remove unused RoomSlot struct and rooms field from web AppState
- Remove unused HashMap import from web main

WZP-S-4: Room access control
- hash_room_name() in wzp-crypto: SHA-256("featherchat-group:"+name)[:16]
- CLI --room flag hashes before SNI, web bridge does the same
- RoomManager gains ACL: with_acl(), allow(), is_authorized()
- join() returns Result, rejects unauthorized fingerprints
WZP-S-5: Crypto handshake wired into all live paths
- CLI: perform_handshake() after connect, before any mode
- Relay: accept_handshake() after auth, before room join
- Web bridge: perform_handshake() after auth, before audio
- Relay generates ephemeral identity at startup
WZP-S-6: Web bridge featherChat auth
- --auth-url flag: browsers send {"type":"auth","token":"..."} as first WS msg
- Validates against featherChat, passes token to relay
- --cert/--key flags for production TLS (replaces self-signed)
WZP-S-7: wzp-proto standalone
- Cargo.toml uses explicit versions (no workspace inheritance)
- FC can use as git dependency
WZP-S-9: All 6 hardcoded assumptions resolved
- Auth, hashed rooms, mandatory handshake, real TLS certs,
profile negotiation, token validation
CLI also gains --room and --token flags.
179 tests passing across all crates.

New identity module (wzp-crypto/src/identity.rs) mirrors featherChat's
warzone-protocol identity.rs exactly:
- Seed: 32 bytes, from hex or BIP39 mnemonic (24 words)
- HKDF derivation: same salt (None), same info strings
- Fingerprint: SHA-256(Ed25519 pub)[:16], same xxxx:xxxx format
- Cross-verified: test proves identity module matches KeyExchange trait
CLI flags:
- --seed <64 hex chars>: use a specific identity
- --mnemonic <24 words>: use BIP39 mnemonic from featherChat
- Without either: generates ephemeral identity
Also adds featherChat as git submodule at deps/featherchat for reference.
32 crypto tests passing (27 original + 5 identity tests).

The --record recv loop was using while-drain which exhausted the jitter
buffer and stopped decoding after the first burst. Now decodes once per
source packet, matching the live mode fix.

- --send-file <file.raw> sends a raw PCM file (48kHz mono s16le) through relay
- Combine with --record: --send-file talk.raw --record echo.raw <relay>
- Fixed all unused import warnings in echo_test.rs
Convert any audio to test format:
ffmpeg -i input.mp3 -ar 48000 -ac 1 -f s16le input.raw

New --echo-test <secs> flag sends a 440Hz tone through relay echo,
records the return, and analyzes quality in 5-second windows:
- Per-window: frames sent/received, loss %, SNR (dB), correlation
- Detects quality degradation over time (compares first vs second half)
- Reports jitter buffer stats (depth, lost, late packets)
- Diagnoses jitter buffer drift and packet loss accumulation
Also exposes jitter_stats() on CallDecoder for diagnostics.

- Reduced jitter buffer min_depth from 25 (500ms) to 3 (60ms) for fast start
- Fixed live recv loop: decode once per source packet instead of draining
the jitter buffer dry (which advanced seq past future packets)
- Fixed Ok(None) handling: connection closed, not "no packet yet"
Live echo test confirmed working with continuous audio.

- --record now handles Ctrl+C: saves PCM file before exiting
- Relay without --remote runs in echo mode (loops packets back to sender)
instead of sink mode, enabling single-relay audio testing
- recv task returns collected PCM via channel for clean file write

- cpal is now behind an 'audio' feature flag (off by default)
- --live mode requires --features audio at build time
- --send-tone and --record work on headless servers without audio libs
- Linux build script no longer installs libasound2-dev
Build for headless: cargo build --release
Build with mic/speakers: cargo build --release --features audio
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
CLI modes:
- --send-tone <secs>: send 440Hz test tone (no mic needed)
- --record <file.raw>: save received audio to raw PCM file
- --help: usage info
- Combine: --send-tone 10 --record out.raw
Raw PCM format: 48kHz mono s16le
Play with: ffplay -f s16le -ar 48000 -ac 1 out.raw
Build scripts:
- scripts/build-linux.sh: Hetzner VPS build with auto-cleanup
- scripts/cleanup-builder.sh: kill stale builders
