Kann ich Motion vibecoden?

Build me a personal task auto-scheduler to replace Motion. Requirements:

- Node + better-sqlite3 + googleapis. Tasks in SQLite: title, duration estimate,
  deadline, priority, done. A small Express page on localhost:4920 to add and edit
  tasks, plus a `plan` CLI command.
- Read my Google Calendar free/busy for the next 14 days (OAuth token cached
  locally); respect working hours 09:00-18:00 and a lunch block, both set in
  config.json.
- The planner is greedy, not clever: earliest deadline first, weighted by priority,
  packing tasks into free slots in 30-minute increments and splitting anything over
  90 minutes into chunks.
- Write the plan back as calendar events with a [plan] prefix. Replanning deletes
  only [plan] events and relays them, never touching real meetings.
- Overdue or unschedulable tasks show in red on the web page instead of being
  silently dropped.
- A 07:30 node-cron run replans the day and emails me the schedule (SMTP in .env).
- Single user, local only, no accounts, no telemetry beyond the Google API calls.
- Out of scope: team scheduling, mobile apps, and meeting-invite handling. It plans
  my solo work around a calendar it treats as read-only truth.
- README: the Google Cloud console OAuth setup. Budget an hour for that alone.
