v0.10.3 — multi-device notes support + safety guards

⚠️ Superseded by v0.10.5 — in this version, foreign-page support only worked for the datetime stamp; the heading conversion silently failed there. Fixed in v0.10.5.

Foreign-page support: notes created on a smaller device (e.g. A5 X notes opened on a Manta) are displayed 1:1 and centered by the firmware — the plugin now maps its zones and the double-tap trigger accordingly. Pages from a larger device are politely refused with a popup.

Safety: OCR replacement refuses any selection that doesn't look like a title (>2 recognized lines / >40 strokes). Fewer screen refreshes per run, lasso overlay hidden during processing, datetime auto-fit, logging off by default.
