ginuerzh 1d42c2ec66 feat(tun): add device write-side self-probe ...

A running tun entrypoint cannot tell a dead device fd from an idle link: both look like frozen stats. The probe writes a self-addressed IPv4/UDP packet (spokeIP->spokeIP, magic+seq) into the device every 30s and reads it back on its own bound socket; sent/acked deltas go to the caller through the metadata probeReport callback. Enabled by metadata probe (default off, gost path unchanged); new probeSent/probeAcked counters (101/102) in x stats.
