fix: pin foliate-js e16530a — desktop double-click zoom toggle

Bump the linuxhg mirror pin from 1305a52 to e16530a (mirror main is
already synced). The fork adds a desktop double-click zoom to the
fixed-layout renderer for all fixed-layout content (comics, manga,
PDFs, fixed EPUBs):

- at fit scale, double-click zooms to 2.5x at the clicked location
- zoomed or panned, double-click resets to 100% centered
- PDF text-layer spans and annotation links keep native double-click
  (word selection) in Smart/Text modes; Pan mode zooms anywhere
- mirrors the existing touch double-tap; disabled in panel-zoom mode
  like the other gestures

Also closes the gap where node_modules was serving a stale tarball
older than the previous 1305a52 pin (missing the toolbar-resize
debounce and selection-drag fixes); a fresh install now resolves the
full set.
