Hyperliquid Connector Stability Upgrade

Shared WebSocket Watchdog

• Implemented a monitoring system that tracks data liveness on active candle streams.
• Automatically triggers a connection reset if no data is received for 5 minutes on high-frequency timeframes (1m, 3m, 5m, 15m), ensuring "silent" disconnects are caught and resolved.
• Includes a 60-second debounce mechanism to prevent rapid "flapping" of connections during intermittent network instability.

Rate Limit Protection

• Added a conservative delay (0.1s) between subscription requests during the reconnection loop.
• This throttling ensures compliance with Hyperliquid's 10 messages/second limit, preventing 429 Too Many Requests errors during initialization or when resubscribing to multiple assets.

Improved Diagnostics

• Added dedicated handling for subscriptionResponse messages.
• The system now explicitly logs successful subscription confirmations and alerts on failures, providing better visibility into the state of active data streams.
