Changelog

Add shared ModalOverlay control to PrivStack.UI.Adaptive replacing

duplicated per-plugin copies in Notes, Tasks, Calendar, and Email.

The control provides animated backdrop, centered card with title bar,

scrollable body, optional footer, Escape key and backdrop-click-to-close.

Built as a code-based Panel (matching EmptyState pattern) with no AXAML

theme file required.

Added case filter to skip *.Tests and *.TestRunner csproj matches in the

dev build script. These are test utilities, not runtime plugins, and

should not be built alongside actual plugins.

ViewModelBase now implements IDisposable with a protected CompositeDisposable

property. Plugins can track subscriptions and event handlers via DisposeWith()

extension method to prevent memory leaks when ViewModels are deactivated.

Added System.Reactive dependency for CompositeDisposable. Added

DisposableExtensions.cs with DisposeWith<T> extension method matching the

ReactiveUI convention.

Move all OAuth client credentials (Google, Microsoft, GitHub) to

environment-variable-only resolution with no compiled-in fallback

defaults. This prevents GitHub push protection violations and ensures

secrets never appear in source code. Added .env.example documenting

required variables. App logs warnings on startup if env vars are missing.

Map "privstack.habits" → "Habits & Goals" in the notification label

switch so habit reminders display with the correct plugin name.
