Read one trailer version's manifest and clips.

Returns one version: every beat in plan order with its cut before the film finish and the take each shot played (takeUrl, its trim, the finished deliveryUrl on a finished master), each with its path in the version's folder and its archivedUrl once copied; its narration, speech clips, music, sound effects and text layer; the trailer's audio timeline; the finish, camera and motion blur it was laid with; every file of the folder (files, manifest.json first); and its zip. A number the trailer does not have is 404 trailer_version_not_found. Every time a trailer's master is published (a preview, an early look or the finished trailer) it is kept as a numbered version, so re-assembling a trailer never loses the master it replaces: the master, and for every beat in order the take each shot played (with its trim, and its finished copy on a finished trailer), the beat's cut before the film finish, its narration, speech, music, sound effects and text layer, and the finish it was laid with. Each version's cuts and takes are copied, untouched, into a folder of their own, one per beat (trailers/<trailer>/versions/<n>-<YYYYMMDD-HHMM>/beats/<NN>-<label>/), with a manifest.json, so a later re-render never loses the clips an earlier version played. Reading versions is free, and a zip of a version's clips is made on request, free. Scope: story:read.
