feat: persist an op log and capture the monitor in-process

The editor now treats the unmutated source plus a JSON op stack as the
working document, so undo survives crash and --file reopen. Monitor
pixels come from ext-image-copy-capture instead of grim; a window pick
is a crop of that frame.

Also records Cut ops, keeps the leading crop under the 100-op cap,
restores notify quoting, and keeps selected handles out from under the
help card after the taller cut-tool legend.

+The renderer, layer surface, clipboard, and monitor capture use Wayland protocols;
+monitor/window discovery currently calls `hyprctl`. The focused output is captured
+in-process through `ext-image-copy-capture` before the layer maps. Selection displays
+that captured frame, while the annotation editor uses
 a translucent layer scrim over the live desktop and draws only the selected capture.
 Another Wayland compositor could support the application after supplying equivalent
 monitor and window discovery; generic Wayland support is not claimed by 1.0.
 
 Runtime commands used by the application:
 
 - `hyprctl`

 - `wl-copy` and `wl-paste`
 - `tesseract`
 - `omarchy-notification-send` when available; saved captures include a thumbnail and
