🤖 Augment PR Summary

Summary: This PR refines the annotation-mode status feedback shown after short stroke/click input.

Changes:

• Repositions the annotation hint popup relative to inkCanvas to avoid DPI-dependent screen-coordinate offsets.
• Adds a transient circular annotation-status indicator popup with a short fade animation.
• Introduces a 30-second idle gate based on the last long stroke.
• Shows the indicator for every short click after the idle period, while suppressing the full text hint during active writing.
• Resets click tracking when a long stroke is committed and after a threshold action fires.
• Stops artificially widening the supplemental dot stroke, retaining the active pen thickness.
• Updates localized setting descriptions to explain the revised interaction behavior.
• Removes the Lite onboarding preset’s explicit override that disabled the annotation-dot hint.

Technical Notes: Both new and existing hint popups use RelativePoint placement with inkCanvas as the target, so offsets are expressed in canvas logical coordinates.
