Voyager 3 schema: the slim catalog (migration 6000, the reset) and blocks (6100)

releases rebuilt without its text copies: poster_id, group_set_id,
bytea keys, source smallint, edge, settled_at as the finish. posters by
id, group_sets. blocks as the lease unit, ranges.block_id. fragments,
range_blocks, release_final, the settler and the fragment merger gone;
release_chunks, rule_counts and rule_samples keyed by block. Cold tables
on CHUNK_TABLESPACE. Migration 6000 truncates the catalog and refuses
without VOYAGER3_RESET=1.
