Connection-stability layer for issue #3. LG webOS WebKit (and other TV-grade clients) miss Engine.IO pongs under decode load with the Socket.IO defaults of 25s ping / 20s timeout, causing spurious transport drops and a connect/reconnect/evict/disconnect loop on the device. Default polling-first transport adds another fragility layer via the polling->WebSocket upgrade dance. - pingInterval / pingTimeout default to 30000 / 30000 (worst-case dead-socket detection 60s, up from ~45s). Both env-configurable via PING_INTERVAL / PING_TIMEOUT. - Player Socket.IO client: transports: ['websocket', 'polling']. Tries WebSocket first; falls back to polling on the same connect attempt if WebSocket fails. Polling fallback preserved for firewall-restricted networks. App-level heartbeat checker is unchanged and remains the safety net for clients that miss the transport-level ping/pong window. Tradeoffs documented in inline comments. README env table extended with PING_INTERVAL and PING_TIMEOUT rows. Refs #3 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
