Description

This PR addresses Issue #576, implementing a predictive RPC health monitoring and failover supervisor within nonce_tracker.py.

Key Modifications

  • Lightweight Asynchronous Probing: Added parallel node-health tracking using non-blocking aiohttp cycles to measure latency shifts without affecting main worker routines.
  • Rolling Moving Averages: Implemented rolling historic window arrays to flag performance drops before a node completely errors out.
  • Preemptive Route Migration: Set up an automated routing selector that smoothly transitions transaction pipelines from degraded primary nodes to secondary fallbacks within 800ms of detection.

Closes #576
