feat: step 7's migration, with an index on spaceId
The first migration since the initial one, created with the CLI (serverpod create-migration --tag studysets), since no MCP bridge was set up yet. On the server it is one transaction that only adds: gen_random_uuid_v7(), the studyset table, the sync engine's tables (spaces, their members and nodes, the CRDT bookkeeping, the log of integrity violations) with their foreign keys, and, from Serverpod v4.0.3, the auth module's profile image foreign key re-created as DEFERRABLE INITIALLY DEFERRED, so that dumps restore. The server tests apply it to their Postgres.
studyset gets an index on spaceId: deleting a space cascades into every synced table, and Postgres doesn't index foreign keys by itself, so account deletion and pruning would otherwise read whole tables. AGENTS.md makes it the rule for every synced table.
The client migration creates each device's SQLite schema. The generator builds it from the whole definition, so it also contains the server's own tables; only the synced tables and the bookkeeping ever hold data on a device.

feat(server): cards and their append-only revisions, synced
Card belongs to a studyset and carries only its position, a fractional index (last writer wins), so cards can be reordered and bulk imports keep their order. Its content lives in CardRevision rows, which are never updated except to blank them (ADR 0001, rule 2): parents lists the revisions a revision replaces (decided: a list, so a revision with two parents resolves a conflict), authorId the writer, reportId the report it answers once reports exist, and the envelope holds the content. Deciding the list of parents and the position now matters: changing a synced table later locks out older app versions.
The migration (created by CLI) only adds: the two tables, an index on spaceId for each (space deletion cascades into them), one for a studyset's cards in order and one for a card's revisions, and the foreign keys, from the space with ON DELETE CASCADE and from the studyset and the card with ON DELETE CASCADE, DEFERRABLE INITIALLY DEFERRED, since synced rows can arrive in any order. The client migration creates the same tables on each device.
