feat: minimal grocery list — add items, check them off

- Groceries DB schema (id, name, checked, created_at) with Drizzle + libsql
- /+page.server.ts: load (unchecked items, newest first), add & toggle actions
- /+page.svelte: text input + Add button, item list with toggle buttons
- Mobile-first styling with scoped CSS classes
- AGENTS.md: project-specific rules including UI validation
