List video destinations.

A destination is where a finished video goes and what it asks of the video: its shape and length, its sound, how it is delivered, what it must show and the checks it must pass. Each one is a row; one whose spec fails its check is listed under unavailable with the reason and is never guessed. specMayBeStale is true when the spec was last checked against its sourceUrls more than 90 days ago (or never): read them again before relying on it. Free; reads only. The same catalog for every account, in order: an app directory's review walkthrough (chatgpt_app_review), a launch trailer, a product demo, a vertical social cut and a website hero loop to start. Each spec holds what the video must show (content), its picture and sound, the end system it is recorded in (host), its delivery, its exports, the checks it must pass and its intent.
