Theorem v1.4.2

Fixed

• Touch selection & swipe gesture decoupling — Fixed glitching and accidental page turns when selecting text to highlight using touch/stylus. In paginator.js, a finger hold (>180ms) now locks the gesture into selection mode and prevents swiping; swipe movement threshold was raised from 8px to 20px with horizontal dominance requirements; and active selections automatically snap the viewport back to full-page alignment if displaced.
• Removed duplicate FoliateEngine swipe handler — Stripped redundant touchend page-turning logic in foliate-engine.ts that competed with Paginator and triggered false page-turns during selection drag gestures.
• Non-blocking highlight overlays — Highlight SVG elements now use pointer-events: none, allowing native touch and mouse selection to freely pass through or cross over existing highlights without interference. Highlight taps continue to be resolved via native document click hit-testing.
