Siavash Sameni 2de6e19956 feat: 6 web client variants — all wire-compatible with WZP protocol ...

3 new WZP-WS variants (speak WZP wire format over WebSocket):
- wzp-ws.js (Variant 4): WZP MediaHeader + raw PCM, no WASM
- wzp-ws-fec.js (Variant 5): WZP + WASM RaptorQ FEC (block=5, symbol=2048)
- wzp-ws-full.js (Variant 6): WZP + FEC + ChaCha20-Poly1305 E2E encryption

Wire protocol compliance (verified against wzp-proto/src/packet.rs):
- MediaHeader 12-byte bit layout: V(1)|T(1)|CodecID(4)|Q(1)|FecRatioHi(1)
- FEC ratio 7-bit encoding across byte0-byte1 boundary
- All fields big-endian (seq u16, timestamp u32)
- Crypto nonce: session_id[4] + seq_be[4] + direction[1] + pad[3]
- HKDF info: "warzone-session-key" (matches wzp-crypto)

Auth flow (matches wzp-relay/src/ws.rs):
- First WS message: {"type":"auth","token":"..."}
- Relay responds: {"type":"auth_ok"} or {"type":"auth_error"}
- All 6 variants handle auth_ok/auth_error text messages

Updated:
- wzp-core.js: detectVariant() accepts ws, ws-fec, ws-full
- index.html: script map + ClientClass dispatch for all 6 variants
- index.html: WASM auto-loading for variants with loadWasm()

URL patterns:
  ?variant=pure       Variant 1: Raw PCM over WS (bridge needed)
  ?variant=hybrid     Variant 2: Raw PCM + WASM FEC (bridge needed)
  ?variant=full       Variant 3: WebTransport + FEC + crypto (no bridge)
  ?variant=ws         Variant 4: WZP protocol over WS (relay direct)
  ?variant=ws-fec     Variant 5: WZP + FEC over WS (relay direct)
  ?variant=ws-full    Variant 6: WZP + FEC + E2E crypto over WS (relay direct)
