v1.5.1

HiBig Zero v1.5.1 — E-Ink UI Revamp

UI Overhaul

• Sub-tab navigation: 5 instant-switch tabs (READING, SENSORS, STANDBY, DEBLOAT, APPS) replace the 10-screen vertical scroll
• Header telemetry: live CPU/DOZE/SENS/BATT status merged into the header bar — tap to refresh, zero background polling cost
• Stepper chips: inline 1-tap chips for Wake/Sleep CPU governor, Doze speed, charge ceiling (75/80/85/90/Custom), and auto-shutdown timeout (1H/2H/4H/8H/Custom)
• Hybrid 2 pills: [ ● ON ] / [ ○ OFF ] and [ ● FROZEN ] / [ ○ ACTIVE ] with unambiguous solid/dashed styling
• Long-press APPLY ALL: long-press the header title → confirmation → apply all rules (zero screen cost)
• Suspend & Alarm Shield: unified card with master toggle + 4 checkboxes (kill Bigme shutdown timer, batch alarms, throttle JobScheduler, instant keyguard lock)
• Keys & Gestures: dual-shortcut card for Custom Side Keys and Gesture Settings (auto-disabled when launcher frozen)

New Features

• Tailscale added to the managed app installer (from tailscale/tailscale-android GitHub releases)
• Instant Deep Doze: force-idle on screen-off, unforce on screen-on via ScreenReceiver
• WhatsApp host added to NetGuard download allow-list

Improvements

• Removed redundant header battery 30s polling timer (telemetry strip handles it)
• DRY_RUN toggle dropped from UI (underlying key preserved as dormant fallback)
• CPU_OPTIMIZER merged into Wake Governor profiles
• Sleep Governor auto-switch enabled when selecting a profile
• Doze modes consolidated: Instant (15s) / Aggressive (5m) / Stock
