Broken-Links Scanner Extension

# Broken-Links Scanner — early release LinkScan.app

Broken Link Checker spots dead URLs inside any text you pick. Highlight a section, hit the toolbar button, and the extension colours broken links pink while showing a neat count.

## Key features
- **Local-only scan** – every check runs in your browser; nothing is uploaded.
- **Fast header probe** – sends a HEAD request, falls back to GET when servers block HEAD.
- **Clear on-page highlight** – broken links gain a pink background so you can fix them straight away.
- **Instant summary** – an alert lists each failed URL and the total found.
- **Selection focus** – works on the part of the page you care about; skip the rest.

## How to use
1. Select text that contains links.
2. Click the extension icon.
3. Review the pink highlights and alert report.

## Current scope
- Checks HTTP/HTTPS links in the selected area.
- Skips `mailto:`, `tel:`, and `javascript:` links for now.
- Full-page mode, exports, and SEO audits are on the roadmap.

## Permissions
`scripting` and `activeTab` let the extension inject a short script and request each selected URL. No other data is touched.

Clean pages, no fuss—give it a try and catch those 404s before your visitors do.
