Screenshots and clips of cmux

cmux shot writes a png or a jpeg of a cmux window. cmux record writes an mp4 or a gif of one. Both capture only cmux's own windows, both go through the same permission-free path, and both work in a release build and inside CI. No Screen Recording permission is involved and none is ever requested.

cmux shot --jpg --max-width 1200 --out ~/before.jpg
cmux record start --gif --max-seconds 8 --label sidebar-drag
cmux record note "dragging the workspace"         # caption, drawn into the clip
cmux record stop
