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).

Changed HKDF expand info strings to match featherChat's identity.rs:
- "warzone-ed25519-identity" → "warzone-ed25519"
- "warzone-x25519-identity" → "warzone-x25519"
Same BIP39 seed now produces identical Ed25519/X25519 keypairs in both
featherChat and WZP. This is the prerequisite for shared identity.
Also added FEATHERCHAT_INTEGRATION.md (1209 lines) from featherChat repo
documenting the full integration plan with confirmed code references.
