James RichandClaude Opus 5 db83c03df6 refactor(mirror): harden rect reassembly and extract the compositor
Third adversarial review pass over the client side.

Rect reassembly moves out of DisplayMirrorManagerImpl into
MirrorRectCompositor: the manager was carrying two unrelated state
machines and 14 methods. Every rect field is now validated before
anything is allocated (total_size is device-controlled), geometry is
latched from the chunk at offset 0 so a later chunk cannot transpose
the blit, continuations must match the buffer that was actually
allocated rather than their own claim, and bounds use the subtraction
form because rect_x + rect_width overflows for hostile values. A rect
that omits width or height covers the full panel in that axis.

remoteKeyInput no longer swallows modified keys, so Cmd+Q, Ctrl+C and
Alt+Tab stay with the desktop instead of being forwarded to the device.

MirrorFrameRenderer tracks colorized runs as a raw Int with a sentinel
rather than a boxed Color?, and MirrorFrame.hashCode includes the
format so a mono and an RGB565 frame of the same size cannot collide.

Drops mirror_view_only, orphaned since MUI gained remote input.
