Select and copy text directly on the page

The text pane is gone: recognised text is selected on the page image like
in a PDF viewer (drag in reading order, double-click a word, triple-click a
line, shift-click to extend, Ctrl+A), copied with Ctrl+C or the context
menu, and previewed in the status bar; on X11/Wayland it also goes to the
primary selection. Middle-drag or Space+drag pans.

OCR asks RapidOCR for per-character boxes and keeps each line's character
boundaries (Line.edges), with Line.locate/quad/word for hit testing and
drawing; lines whose boxes don't match the text fall back to even spacing.

Errors are logged to the terminal with their traceback, and Ctrl+C in the
terminal closes the app (restoring mouse mode), dismissing any open dialog.
