The image fills the 94% viewer with a transparent letterbox, so taps on
the dimmed canvas beside the image hit the viewer and did nothing — only
the 6% margin dismissed. Add onTapUp that dismisses when the tap lands
outside the actual painted-image rect (computed from the RenderImage +
applyBoxFit, transformed for any zoom/pan). Double-tap reset, scroll
zoom, pan, Esc, and the close button are unchanged.

The inline image cards (T-249) are often too small to read. Clicking one now
opens a full-screen lightbox: zoom (scroll wheel / pinch), pan when zoomed,
double-click to reset to fit, Esc / close button / backdrop click to dismiss.
ClideLightbox is a reusable primitive (lib/widgets/) over Flutter's
InteractiveViewer with clide-owned zoom gestures, shown via the DialogRouter
(dimmed backdrop, single modal at a time, D-78). The card stays display-only;
the click is a navigation gesture, not an inline control.
CLI parity (D-6): `clide image show <path> --fullscreen` opens straight into
the lightbox instead of injecting a card.
