Read a table read's share link.

Returns ONE screenplay version's (scriptUploadId) table-read share state: the active public link if the read is shared — its shareUrl, audience, playback descriptor (mode, scope, scene/entries), expiresAt, includeOnProfile flag and the render status of its MP4 (theater) or scoped MP3 (audio) — or share: null when it is not shared. jobId names the table read the share resolves to (the script's latest read), null when there is none. A script that is not yours is 404, the same as one that does not exist. The same read the Writers Lab's share dialog, MCP get_script_share and sleeperhit script share get make. Read-only; costs no credits.
