- Fix#52: Watchdog proxy restart on single URL failure:
* Validate failure against secondary independent probe URL before declaring proxy down
* Skip restart when direct WAN is also degraded or down (!direct_ok)
* Implement 120s cooldown between automated proxy restarts
* Fix Telegram notification to accurately state 'Перезапуск sing-box' instead of 'Перезапуск роутера'
- Fix#51: Telegram bot spamming WAN up/down notifications:
* Filter hotplug events strictly by badwan_monitored_interfaces (defaults to wan)
* Add atomic directory lock with debounce delay and real ubus state query
* Prevent repeated notifications when interface state has not transitioned
- Feat: 2-VPN deadlock elimination & self-download subscription proxy:
* Isolate unbootstrapped dependent subscription sections on initial boot (deferred_sections)
* Allow self-download proxy target for subscriptions with explicit UI hint '(текущее правило при активности)'
* Enable automatic local proxy fallback for subscription refresh when direct WAN download fails while sing-box is active
* Add regression test in tests/subscription_bootstrap_deadlock.sh
- Fix: Parental control quota enforcement:
* Correct route rule filtering when daily quota minutes are exhausted without a fixed time interval
- i18n & Version bump:
* Bump fe-app-tachyon to 1.3.26 and update Russian PO/POT translations
