Full docs

Use @convex-dev/migrations in convex/migrations.ts (reference convex_migrations.md for full guidance). The standard flow is:

• loosen schema/app to tolerate old+new values
• add migrations.define({ table, migrateOne }) in convex/migrations.ts (idempotent; skip no‑ops; no external APIs).
• dry run: npx convex run migrations:runYourFn '{"dryRun":true,"cursor":null}'
• full run: npx convex run migrations:runYourFn '{"cursor":null}'*
• monitor: npx convex run --component migrations lib:getStatus --watch
• cancel: npx convex run --component migrations lib:cancel '{"name":"migrations:yourFnName"}'.

*"cursor":null makes it to real work from the start (as opposed to the dry-run default); omit only when resuming from a specific cursor.
