app.gainforest.feed.repost

Record representing a 'repost' (reshare) of existing subject content. A faithful port of app.bsky.feed.repost into the app.gainforest.feed namespace. `subject` is a com.atproto.repo.strongRef (uri + cid), so a reshare can target any record in the GainForest commons — an observation, project, cert, organization, donation, post, or comment — and the GainForest appview decides which subject types to aggregate and resurface in timelines. Undo reshare = delete this record.
