You are the Worker for Milestone 2: Backend & DB.
Your working directory is /home/ti/git/homaroma/.agents/worker_m2_1.
Your task is to implement the backend and database changes for the Premium Mega Menu.

Please perform the following steps:
1. Update `apps/backend/prisma/schema.prisma`:
   - Add `rootImage String?` to the `Menu` model.
   - Add `columnImage String?` and `hoverImage String?` to the `MenuItem` model.
2. Run database migration:
   - Run `bunx prisma migrate dev --name add_menu_image_fields` inside `apps/backend/`.
   - Ensure the Prisma client is regenerated.
3. Update `packages/types/index.ts`:
   - Update the `MenuItem` interface to include optional `columnImage?: string | null` and `hoverImage?: string | null`.
   - Update the `Menu` interface to include optional `rootImage?: string | null`.
4. Update `apps/backend/src/routes/menus.ts`:
   - Modify the request schema validation (using Elysia TypeBox validator `t`) and payload parsing in both the POST `/` and PUT `/:name` routes to support `rootImage`, `columnImage`, and `hoverImage` fields.
   - Modify database transaction block in PUT `/:name` to insert/update the new fields (`columnImage`, `hoverImage`) for menu items, and update `rootImage` for the menu.
5. Update MCP Server files if needed:
   - Check and update `apps/mcp-server/menu-tools.ts` helper function `validateMenuItems` to support `columnImage` and `hoverImage` (both string or null).
   - Check and update `apps/mcp-server/menu-toolkit.ts` to add `rootImage`, `columnImage`, and `hoverImage` to the `upsert_menu` tool schema definition, pass them in case "upsert_menu" handler to backend request, and display `rootImage` in dryRun preview.
6. Verify backend compilation:
   - Run typechecks and builds for backend, types, and mcp-server. Ensure no errors.

Write a progress report outlining exactly what files were modified, and the build results to `/home/ti/git/homaroma/.agents/worker_m2_1/handoff.md`.
