Release notes

• Fixed connection startup to fail fast with a clear controller outage message instead of hanging or showing internal probe details.
• Restored immediate posture enforcement after VPN connection and prevented stale controller auth keys from crossing registrations.
• Improved Windows posture collection reliability and crash handling so disconnect state is reflected correctly in the UI.
• The app now tears down the VPN tunnel promptly when exiting.
• Strengthened watchdog safeguards around local process verification, background health checks, and service recovery.
• Fixed a macOS issue where the VPN service could get stuck in a reinstall loop — connections now recover cleanly.
• The agent now restores itself automatically if its background service record ever goes missing, so you no longer need to reinstall when that happens.
• Improved stability of background processes with smarter restart behavior under intermittent failures.
• Crisper system tray icon on macOS — smaller, better proportioned, and sharper on high-DPI (Retina) displays.
• Improved Windows posture check reliability by preserving complete process evidence while keeping startup-safe fallback collection paths.
• Faster network fallback behavior during connectivity recovery, reducing fallback transport delay to improve responsiveness.
• Added clearer watchdog timing diagnostics around local process collection to improve troubleshooting on slower machines.
• Small polish and reliability improvements under the hood.
