Migrate PdfCraft to egui 0.37 with reconciled platform and editor behavior

Preserve current main, pin the reviewed forks, and cover hidden input,
IME lifecycle, bidi rendering, persisted settings, and editor geometry.

Repository gates pass; native/browser acceptance and paired app performance
remain explicitly open for human review.
