PDFeverything v1.3.9 — Zoom Scale Fix

PDFeverything v1.3.9

🐛 Critical Fix

• Zoom scale calculation corrected — deleted _smooth_scale_all which used _fw_ratio as a fixed scale base. Pixmaps can be at ANY zoom level (fit_height/fit_width/arbitrary %). All three zoom paths now compute scale = new_factor / old_factor based on _current_zoom_pct().

⚡ Performance (v1.3.8–1.3.9)

• LRU cache (OrderedDict) with memory tracking (250MB cap, 180MB target)
• Dual-timer page tracking: throttle 30ms (rough) + debounce 150ms (bisect)
• On-demand prefetch of N±1 pages
• Two-pass zoom: instant QPixmap.scaled() + deferred PyMuPDF re-render
