Aaron Johnson 8285e0f45b Add Prometheus metrics for packet fragmentation monitoring in nodes 
- Add comprehensive VL1 (ZeroTier protocol) fragmentation metrics:
  * Track fragmented packets, fragments, reassembly failures
  * Monitor fragment ordering issues and duplicates
  * Histogram for fragments per packet distribution

- Add VL2 (TAP/Ethernet) fragmentation metrics for virtual ethernet interfaces:
  * Track oversized frames from TAP devices
  * Monitor frames that would fragment or drop
  * Histogram for frame size distribution with common MTU buckets

- Integration across all TAP implementations (Linux, Mac, BSD, Windows)

This allows monitoring of fragmentation patterns for nodes participating
as members in ZeroTier networks, helping identify MTU mismatches and
optimize virtual ethernet performance.
