Realtime non-archival relay for third-party AT Proto PDSes.

In the interest of cost control, we are scaling down the network:

• Only PDSes with fewer than 1000 repos are crawled
• We do no backfilling, only current events are relayed to consumers
• Stale data (≈ 24hrs?) is purged from the database [not doing this yet]

The idea is that we can have apps with much larger limits if we scale down the volume of the network.

• Large block sizes
• Large record size limit
• therefore: Large text field in post records, large uploads
• etcetcetc

todo

• metrics / tracing / observability shit
• history:
  • store indexedAt values
  • purge based on ttl
  • takedowns
