Adds a recording harness for the Emacs session alongside the terminal one, and the capture it produces: a declaration added to rt_scene.h, the fourteen translation units across four targets that the depfiles put downstream of it, and the link steps that do not rerun because the objects come back byte identical. Both harnesses waited on xdotool search --sync for their window, which blocks indefinitely rather than failing when the window never appears, so a recording that went wrong hung instead of exiting. Replaced with a bounded poll.
