Vale construir sua versão de GatherOS?

Build me a personal visual reference library for macOS to replace GatherOS. Requirements:

- Use Electron + React + TypeScript + Vite with better-sqlite3, sharp, and node-vibrant; do not offer alternative stacks.
- Make the core loop work end to end: paste or drag in an image, save a screenshot with Command+Shift+S, or paste a URL, then keep the original, thumbnail, title, source URL, and content hash.
- Store metadata in SQLite and media under ~/Library/Application Support/ReferenceShelf/; include collections, tags, notes, soft-delete trash, ZIP export, and a restore-safe backup command.
- Show a keyboard-friendly masonry library with All, Unsorted, and Trash views, bulk tag or collection actions, an item detail panel, and a source link.
- Add SQLite FTS5 search for title, source, notes, and tags, plus palette extraction with color filters;
  keep these working with no network or AI.
- Add one bounded Spaces board with pan, zoom, image cards, text, sticky notes, shapes, autosave, and PNG export;
  store board positions as JSON.
- Use an optional OpenAI API key from .env for title, tag, and embedding jobs; if the key is absent,
  show a clear disabled state and keep the local search usable.
- No accounts, no telemetry, no cloud sync, and everything stays on my Mac except explicit OpenAI calls.
- Out of scope: X, Instagram, and Cosmos imports, mobile clients, multi-device sync, and the full browser-extension/native-messaging bridge;
  keep URL capture as paste or drag.
- Include a README with install commands, Screen Recording permission steps, the data directory, backup and export instructions,
  OpenAI data handling, tests, and known limitations.
