Changelog

Move ToastContainer from the root Panel (centered on entire window)

into the Grid.Column=1 content area Panel so toasts center on the

plugin view regardless of sidebar state.

Dismiss button: match the type icon's layout — 16x16 panel, centered

vertically, symmetric margin (10,0,12,0 mirroring 12,0,10,0), same

StrokeThickness=2. Both icon and dismiss are now vertically centered

instead of top-aligned.

Entrance: slide down from -40px with BounceEaseOut easing (0.4s) for a

subtle bounce effect. Exit: slide up -30px + fade out (0.3s) before

removal from collection.

ToastService now raises DismissRequested so the container can animate

out before the toast is removed. Manual dismiss clicks, action button

clicks, and auto-dismiss timer all use the same animated path. A

HashSet tracks in-flight dismissals to prevent double-dismiss races.

Hide the FriendlyLabel TextBlock when empty so the StackPanel

spacing doesn't push the message text down.

Info toasts now show only the message without a header label.

Success/Warning/Error toasts retain their labels.

The script ran dotnet run as a foreground process, but with

set -euo pipefail, bash's default SIGINT handling could leave

the child process running. Now the app is launched in the

background with an explicit trap that forwards SIGINT/SIGTERM

to the child PID and waits for it to exit cleanly.
