+"""Fix users.id UUID->text type mismatch for Better-Auth compatibility.
+
+Better-Auth generates nanoid-style text IDs (e.g. pGud2ln2WAFHC0KYjBVKR4Rc7mM8OcTI),
+but the users table was using PostgreSQL uuid type. When Better-Auth tries to INSERT
+a new user, Postgres throws:
+  ERROR: invalid input syntax for type uuid: "pGud2ln2WAFHC0KYjBVKR4Rc7mM8OcTI"
+
+The sessions, accounts, and verifications tables already use text IDs — only users,
+user_store_accounts.user_id, and purchases.user_id needed fixing.
