Can I vibecode Raindrop.io?

Build me a personal bookmark manager to replace Raindrop.io. Requirements:

- Node.js 22 + TypeScript: a Fastify server and a React front end built with Vite.
  `npm start` serves http://localhost:4620.
- Storage: better-sqlite3 in ./data/bookmarks.db with an FTS5 index over title, note, tags,
  URL and saved page text. Page copies go to ./data/archive/<id>/.
- Saving a URL: fetch it, read title, description, favicon and og:image, extract the article
  with `@mozilla/readability` + `jsdom`, and keep the cleaned HTML with its images downloaded
  next to it, so the page still opens when the site dies. Run this in a background queue so
  saving returns at once.
- Collections nested up to 3 levels, tags, favourites and one note per bookmark; drag a
  bookmark onto a collection to move it. Grid, list and headline views; sort by date, title
  or domain.
- Search box with `tag:`, `in:<collection>` and `domain:` operators plus plain text over FTS5;
  results show a highlighted snippet.
- Highlights: select text in the saved copy to store a coloured highlight with an optional
  note, and list every highlight of a bookmark.
- Maintenance page: a duplicate finder (same URL after dropping utm_* parameters and a
  trailing slash) and a broken-link check (HEAD with GET fallback, 10 s timeout, 5 at a time)
  that tags dead links.
- Import the HTML or CSV export from Raindrop (folders become collections; keep tags, notes
  and created dates) and export both formats again.
- extension/: a Manifest V3 Chrome extension that saves the current tab to localhost using a
  shared token from .env.
- Single user: one password in .env and a signed cookie. No accounts, no telemetry, local-first.
- Out of scope: sharing, mobile apps, reminders, AI tagging.
- README: setup, where the data lives, loading the extension unpacked, and backing up ./data.
