+page.test.ts triggered svelte-kit sync's route walker (which treats
any +-prefixed file as a route). Renaming to login.test.ts lets the
sync pass without disabling it in scripts, preserving the upstream
guarantee that types in .svelte-kit/ are fresh before check/test.
Plan bug introduced in Task 10 (filename chosen in the plan); fixing
here and updating the plan so re-runs use the correct name.
