Arch-v0.3.0: Release v0.3.0

Changelog

v0.3.0

• Implemented dwell clicking with a translucent floating palette offering
  left, double, right, and middle clicks, drag, pause, and layout flip.
• The palette can be repositioned hands-free: dwell on its grip to pick it
  up, let it follow the cursor, then dwell again to drop it.
• Face tracking is now optional and persisted per profile, so PowerMouse can
  be used for clicking alone alongside any pointing device.
• Dwell and voice clicking keep working when the camera is unavailable.
• Dwell settings (dwell time, radius, palette opacity, and orientation) are
  persisted per profile.
• Tracking parameter controls are greyed out while face tracking is off.

v0.2.0

• Implemented voice clicking.
• Several UI and UX improvements.
• Fixed the FPS count for the camera widget.
