Initial commit: AeroFetch — yt-dlp/YouTube downloader for Windows

Electron + React (Fluent UI) desktop frontend for yt-dlp:
- Download queue with live progress, concurrency cap, cancel/retry
- Format/quality picker via yt-dlp probe; audio extraction to MP3
- Settings + history persistence (electron-store / JSON)
- Clipboard link auto-detect; persisted light/dark theme
- NSIS + portable packaging (binaries bundled at build time, not in git)

UI: "Studio" sidebar layout with a toffee-brown theme (light + neutral dark).
Dropdowns use a native <select> and tooltips a CSS-only Hint, to avoid a
dev-machine GPU overlay flicker/blank issue.
