Mini Browser Popup

# Mini Browser Popup

Open any URL as a clean popup window (no Chrome toolbar). Configure URL, window size, and screen position.

## Features
- Popup window (`type: "popup"`) for a mini‑app feel
- Configurable URL, width, height, top, left
- Smart URL normalization (adds `https://` if you omit it)
- First‑run flow: opens Settings once; later clicks open popup directly
- Minimal permissions: `storage`, `contextMenus`
- No data collected, no analytics, no remote code

## How to use
1. Click the extension icon → Settings opens the first time
2. Enter your URL (e.g., `google.com`) and preferred size/position
3. Click **Save** (or **Open Now**). After that, clicking the icon opens your popup window immediately.
