v1.1.0 — reliable detection, no cursive false positives

What's new

• Reliable scribble detection — no more cursive false positives. Detection now keys on direction consistency: a scribble is a single back-and-forth zig-zag (segments along one axis), while handwriting — including dense cursive — goes many directions. Calibrated on a corpus of real strokes (0 false positives, 0 false negatives). It's instant (no page read while writing) and works at any angle. Only zig-zags are recognized — a single strikethrough or an X/cross is intentionally not treated as an erase.
• Landscape: erase is skipped (not supported yet). In landscape the device shows a split half-page and the host's lasso pipeline misbehaves there (it can hang), so a scribble in landscape shows a brief notice and does nothing instead of risking a freeze. Erase works in portrait.

Install: copy scribble.snplg to your Supernote, then Settings → Plugins → Install plugin → select it → Install.
