GitHub Repository Alphabetizer per TjAce

GitHub Repository Alphabetizer
A small Firefox extension that sorts the repository list on GitHub's home/dashboard page alphabetically.

What it does
- Watches github.com pages for repository lists
- Reorders matching repo cards/items by name
- Leaves the rest of the page alone

Notes
- This extension is scoped to github.com
- It is intentionally lightweight and does not require a popup or options page
