Language Switcher for Microsoft Learn per mkdev

🔧 Technical Feature Summary
- Browser extension to quickly switch display language on Microsoft Learn
- Supported browsers: Chrome / Edge (via Chrome Web Store), Firefox (including mobile)
- Triggered via extension icon or context menu
- Rewrites the language code in the URL (e.g., en-us ↔ ja-jp) to redirect the page
- If any non-en-us language page is opened, it will always redirect to en-us automatically
- Options page allows users to set a preferred target language to switch from en-us
- Supported targets: ja-jp (Japanese), zh-tw (Traditional Chinese), ko-kr (Korean), fr-fr (French), ru-ru (Russian), uk-ua (Ukrainian)
- When switching language, users can choose whether to open in a new tab or update the current page
- Both language and tab behavior settings are saved via storage API and used across the extension
- Only works on the domain learn.microsoft.com
- Does not provide translation itself — it simply redirects to the appropriate Microsoft-hosted localized page
