* feat(reader): add middle mouse button autoscroll in scrolled mode Middle-clicking a book in scrolled mode on desktop apps plants an anchor indicator and scrolls with a velocity proportional to the pointer's distance from it, like browser autoscroll (#4951). A quick click sticks until the next click, wheel, or Escape; press-move-release scrolls only while held. Vertical-writing books autoscroll along the horizontal axis. The middle button's default is suppressed while the feature is armed so WebView2's native autoscroll cannot double-drive on Windows. A new Middle-Click Autoscroll toggle in the Scroll settings section (desktop only, default on) turns it off. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(reader): drop the middle-click autoscroll toggle Middle-click autoscroll is a common desktop convention and middle click has no other use in the reader, so it is always enabled on desktop apps in scrolled mode instead of being a setting.

Keys the scanner would prune (strings it cannot see statically on this branch) are left untouched.
