feat(browser-extension): webpages capture with markdown conversion (#548)10-31-feat_browser-extension_webpages_capture_with_markdown_conversion

Improved browser extension memory saving with better content handling and added markdown conversion.

### What changed?

- Enhanced memory content handling in the background script to prioritize different content types (explicit content, highlighted text, markdown, HTML, or URL)
- Added HTML to markdown conversion using TurndownService when saving entire pages
- Improved HTML handling by removing script tags before processing
- Updated the web app to display the saved URL from metadata when available
- Added turndown library and its type definitions as dependencies
