v3.8.0

Release v3.8.0

• fix(tun): restore clash-tun route on mihomo respawn in TUN/MIXED mode

Replace one-shot _spawn_tun_route_daemon with a lightweight one-shot
background watcher (_wait_and_set_tun_route) called on every procd
respawn via service_started. Fixes UDP blackout after mihomo restarts
in TUN and MIXED proxy modes.

• feat(hotplug): add 40-clash hotplug script

Automatically updates HTTP proxy-providers and rule-providers via
mihomo REST API when WAN interface comes up. Handles PPPoE late start,
reads API port and secret from config.yaml, URL-encodes provider names,
filters out non-HTTP (static) proxy providers by vehicleType.

• feat(log): show clash-hotplug entries in log viewer

Extend processLogLine regex to match clash-hotplug tag (no PID suffix).
Add orange marker 🟠 for hotplug log entries.
