-- Roadmap status enum gains a fourth value `considering` for items that are
-- under discussion but not yet committed to. Same migration also renames
-- the existing `beta` value to `in_beta` so the canonical names line up
-- with the v4 spec (no second display label layer needed).
--
-- SQLite can't widen a CHECK constraint in place, so this is a full table
-- rebuild. roadmap_attributions has an ON DELETE CASCADE FK to
-- roadmap_items(id), so foreign keys are toggled off around the rebuild to
-- preserve attribution rows across the DROP/RENAME.
