Prostore::Steps::Kind::AlterEnumMembers
Swap the CHECK constraint on an enum column to reflect a widened
member set (ADR-0016). Postgres uses DROP CONSTRAINT … ADD CONSTRAINT
in a single transaction; SQLite uses the table-rebuild dance. The
field snapshot carries the final desired metadata (members, flags,
portable type) so the executor can render the new CHECK and update
the bookkeeping row.
