voyager 3: release_texts, the searchable strings of a release (migration 6200)

One table and one trigram index for every string search matches against:
the release name (kind 1, stored once more) and what anyone learns later
(the prober's file names inside an archive, NFO titles, par2 set names,
media titles), appended by insert, never an update of the releases row.
Kinds and the per-kind cap in lib/release/text_kind.ts (textsToStore).
The judge's dirty mark follows an insert or delete. Migration 6000 loses
its two trigram indexes on releases.
