0733efd186 Add umedbazarov/ruh-vpn: VPN/proxy manager for sing-box (#304)
* Add umedbazarov/ruh-vpn: VPN/proxy manager for sing-box

New community plugin: bar widget, panel, service and control-center
shortcut for managing SSH, VLESS, VMess, Shadowsocks and SOCKS5
connections through sing-box, with routing presets, custom rules,
system-proxy/TUN modes and a kill switch. The bundled Python backend
serves a loopback control API protected by a per-launch bearer token.

* Address review: sanitize kill-switch ruleset, scope TUN capability, fix mux error path, disclose DNS

- kill switch: only pre-resolved, canonicalized literal IPs enter the nft
  ruleset; domains are resolved first and anything unparseable is dropped,
  so subscription-supplied addresses can no longer inject nft syntax
- TUN: CAP_NET_ADMIN is granted to a plugin-private copy of sing-box in a
  0700 directory instead of the shared system binary; the copy is refreshed
  (clearing the cap) when the system binary changes, and the legacy grant
  on the shared binary is removed in the same polkit prompt
- fix NameError in the mux startup failure path (undefined mux_name) that
  hid the log tail and skipped teardown
- README: disclose plain-UDP DNS endpoints (8.8.8.8 via tunnel, 223.5.5.5
  direct in rules mode) alongside the TUN DoH endpoint
