List a product project's product video plan runs and what may be planned.

The project's plan runs (newest first) and what may be planned next: the feature map to choose from (each feature's id, name and availability) and the eligible capture count per shape ({ '16:9': n, '9:16': n, '1:1': n }) — a shape with none cannot be planned into. Planning a product video turns one feature of the project's feature map, or a named release and its features, and the project's recorded captures into an ordinary draft trailer — each beat names its capture, the stretch of it it plays, a narrated line, whether the beat keeps its own sound, and its depth — and it is free: it answers at once, the run is polled until it is ready, and the result is an ordinary capture-only draft trailer approved with approve_trailer_plan. A read: it never plans, renders or edits. Scope: story:read.
