/**
* Selects the most suitable exit node from a list of ping results.
*
* The selection algorithm follows these steps:
*
* 1. **Filter Invalid Nodes**: Excludes nodes with errors or zero weight.
*
* 2. **Sort by Latency**: Sorts valid nodes in ascending order of latency.
*
* 3. **Preferred Selection**:
* - If the lowest-latency node has sufficient capacity (≥10% weight),
* check if a previously connected node is also acceptable.
* - The previously connected node is preferred if its latency is within
* 30ms or 15% of the best node’s latency.
*
* 4. **Fallback to Next Best**:
* - If the lowest-latency node is under capacity, find the next node
* with acceptable capacity.
*
* 5. **Final Fallback**:
* - If no nodes meet the capacity threshold, fall back to the node
* with the highest weight (i.e., most available capacity).
