[FY25-26 WE6.1.4] Establish Pretrain production design for MVP

- This week focused on discussion around automated supervision, which we anticipate will provide a key risk mitigation for unattended Pretrain deployments. Automated supervision of MediaWiki deployments (not yet public) contains a high-level sketch of what this may look like in the near term, focused mainly on practical concerns (i.e., bridging between our current supervision tools and what we want for Pretrain).
