fix(scan): launch AE with the project as arg to bypass the Home screen

afterfx -r alone leaves AE on its empty Home/Start screen, which blocks the
script from running (AE sits idle on Untitled Project until the scan times out).
Now launch 'afterfx <aep> -r scan.jsx' so the project opens directly; scan.jsx
uses the already-open project and only app.open()s as a fallback.
