v0.3 stable

Changelog

[Unreleased] - 2025-12-16

Added

• Custom Pull-to-Refresh: Implemented a custom refresh indicator on the Dashboard that spins the app icon (assets/icon.png) during refresh.
• Startup Alert Checks: The app now immediately checks system health upon Dashboard load. If a system is already overloaded (>80%) when the app starts, an alert is triggered instantly.
• Safe Initialization: Added postFrameCallback to Dashboard initialization to ensure the UI renders immediately before starting heavy background services (preventing startup freezes).

Changed

• Alert Thresholds: Updated CPU, RAM, and Disk alert thresholds to a uniform > 80% (previously mixed 60%/80% rules).
• PIN Security Flow:
  • Restored PIN Code functionality.
  • Added automatic PIN cleanup on Logout to prevent "Ghost PIN" issues (asking for a PIN from a previous user).
• Alert History: Capped local alert history to 50 items to improve load times and performance.

Fixed

• Startup Crash: Resolved Unhandled Exception: Widget has been unmounted by correctly passing the active BuildContext during the PIN success callback.
• Emulator Freeze: Diagnosed and mitigated initialization performance issues that were causing white-screen freezes on slower emulators.
• Duplicate Code: Removed duplicated logic in DashboardScreen related to the refresh indicator.

Documentation

• README: Completely rewritten to reflect the current feature set, tech stack, and new capabilities.
