- Perf(watchdog): Adaptive external health checks for proxy (30s) and DNS (60s)
* Honor UCI ai_proxy_health_interval and ai_dns_interval while healthy
* Adapt to fast retry (10-15s) upon consecutive failures, instant post-heal reset
* Single shared observation context (tick_context) per tick eliminating redundant pgrep/proc scans
* Throttle watchdog keepalive file writes from 5s to 30s
- Perf(ui): Read-only fast path for get_ui_state
* Decouple refresh_action_dirs() filesystem GC from 500ms polling requests
* Throttle action directory cleanup to once per 30s via /var/run stamp
* Trigger immediate GC sweep on action job completion
- Perf(telegram): Long-poll 50s and eliminate redundant sleep after success
* Increase getUpdates long-poll timeout to 50s (curl timeout 65s)
* Remove redundant sleep after successful poll for instant command responsiveness
- Perf(torrserver): Cache detected PID and replace shell sleep with native ucode sleep(60000)
- Fix(singbox): Remove harmful hijack-dns rules from mixed proxy inbounds
* Eliminate hijack-dns (port 53 / protocol dns) from section, direct bypass and service mixed proxies
* Resolve 4-5s curl timeouts on component updates (api.github.com) and slow LAN DNS resolution
* Maintain ip_is_private: true direct LAN routing bypass
- Test: Add tests/watchdog_adaptive_intervals.sh and update tests/sing_box_runtime.sh
- Version: Bump fe-app-tachyon to 1.3.27
Fixes regression from 1.3.25 where section mixed proxy inbounds lost internet access due to missing DNS hijacking and missing private IP bypass, and suppresses noisy log warnings during service restart/update.
