Can I vibecode Hootsuite?

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

- Node.js 22 + TypeScript: a Fastify API, a React front end built with Vite and a separate
  worker process. `npm start` serves http://localhost:4950; `npm run worker` publishes due posts.
- Storage: better-sqlite3 in ./data/social.db with accounts (network, handle, encrypted
  tokens), posts (body, media paths, status, scheduled_at, timezone) and post_targets (post,
  account, status, remote id, error).
- Tokens are encrypted at rest with AES-256-GCM (Node crypto), the key in TOKEN_KEY in .env.
  Client ids and secrets also live in .env.
- Networks, in this order: Bluesky (app password through `@atproto/api`), Mastodon (access
  token), LinkedIn (member posts through OAuth with `w_member_social`), then Facebook Pages and
  Instagram Business through the Meta Graph API. Each sits behind a `Publisher` interface with
  `validate(post)` and `publish(post)`. X is not included.
- Composer: one text box with per-network character counters (Bluesky 300, Mastodon 500 by
  default, LinkedIn 3,000), up to 4 images with alt text, and a date and time picker in the
  chosen timezone.
- Calendar: week and month views, drag to reschedule, statuses draft, queued, published and
  failed, and a retry button on failed targets.
- Worker: poll every 30 seconds, lock a due post before sending, retry failures 3 times with
  backoff, never publish the same target twice.
- Single user, one password in .env. No accounts, no telemetry, local-first. Outbound calls:
  only the networks you connect.
- Out of scope: unified inbox, listening, analytics, approvals, TikTok, X, video.
- README: creating each developer app (Meta apps stay in development mode for your own
  accounts), redirect URLs, and a warning that LinkedIn and Meta tokens expire and must be
  re-authorized.
