This initial commit sets up a browser extension that extracts track, artist, and album data from webpages and submits it to the Last.fm API, with midomi.com wired in as the first supported site. It includes the full extension scaffold: background handling, content-script scraping via XPath, a credentials flow that stores only the Last.fm session key, and install/options UI pages. For developers following the project, this establishes the end-to-end architecture and a clear path to add support for more sites next. Practical effect: the project now has a working MVP instead of just an idea.
