Can AI replace Post Bridge?

Build me a personal social post scheduler to replace Post Bridge. Requirements:

- Node + Express + better-sqlite3; a localhost page with a compose box,
  image/video attach, and the queue ordered by send time.
- Targets with open APIs only: Bluesky (app password via @atproto/api),
  Mastodon (access token), and a Telegram channel (bot token). Creds in
  .env, one small adapter file per network so a fourth is addable later.
- For the approval-gated platforms people actually want (TikTok, Instagram,
  YouTube, Facebook, Threads, Pinterest, LinkedIn), do NOT fight their APIs:
  at post time send me an ntfy.sh push with the caption and media path so I
  can post by hand in a minute. Say clearly in the README that these need
  approved developer apps and business verification you cannot one-shot.
- Slot-based queue: I define posting times per weekday in my timezone and
  new posts fill the next free slot; a post can also be pinned to an exact
  datetime or duplicated across networks with per-network text and counts.
- A node-cron tick every minute publishes due posts, marks each row sent or
  failed, retries failures 3 times with backoff, and marks before sending so
  nothing double-posts.
- Attached media stored in media/ next to the database, images resized per
  network with sharp.
- A history page of the last 100 sent posts linking to the live posts.
- Runs on my always-on box; localhost only, no accounts, no telemetry.
- Out of scope: cross-network analytics, teams, and per-platform video
  transcoding.
- README: getting a Bluesky app password, a Mastodon token, and a Telegram
  bot token, plus an honest note that social APIs drift and this needs
  occasional patching.
