Artifact pre-rendered vintages

The pre-rendered as_of dates for one (slug, subject_id), with the formats stored under each date and their object URIs. Read-only: no render is triggered by asking. Pre-rendered subject kinds (filers, cohorts) have no live loader, so a caller must know which dates exist. For cohort subjects as_of=latest on the render call resolves to the newest date listed here; for filers pass one of these dates explicitly. Both spellings of a filer id are searched and merged. Authentication: API key or session. Unmetered. Billing: Free.
