Can I vibecode Typefully?

Build me a tweet composer and scheduler like Typefully. Requirements:

- A local web app: compose posts and threads with live character count per
  post, split threads with "---", drag to reorder, image attachments, and a
  clean distraction-free writing view with drafts autosaved to SQLite.
- A queue: pick a time or "next free slot" (slots defined in a config file,
  e.g. weekdays 9:00 and 16:00). Calendar-style queue view grouped by day.
- Publishing via the X API v2 (keys in .env) · with an honest README section:
  the free API tier is read-only; posting needs the paid tier, which costs
  more than Typefully. Include a fallback "copy thread to clipboard" button
  and a browser-notification reminder at slot time so the tool stays useful
  without paying X anything.
- A cron-style loop in the same process publishes due queue items and marks
  results (posted / failed with error).
- Single Node process, no accounts, runs on localhost or a VPS.
