🤖 Augment PR Summary

Summary: This PR expands board roaming, annotation status guidance, and external-protocol shortcuts.

Changes:

• Adds two-finger zoom and rotation controls to the roaming popup, persisted in gesture settings.
• Routes roaming stylus contacts through a new single-/two-finger gesture state machine.
• Extends roaming transforms to apply translation, scaling, and rotation to ink and canvas media.
• Replaces the annotation hint popup with a non-modal, positionable MessageBox helper and a transient status dot.
• Adds URI commands for the video booth and annotation modes.
• Adds desktop-shortcut creation UI and generated feature-specific ICO badges.
• Indexes nested settings-expander items for settings search and updates localized copy.

Technical notes: The new MessageBox APIs support explicit screen positioning, automatic work-area clamping, optional auto-close, and owner/topmost propagation.
