Nested star lists for GitHub per Injae Ryou

GitHub star lists are one level deep. This extension reads a naming convention parent/child and draws your star lists as a collapsible folder tree, so the structure you already meant is the structure you see.

• Folder tree on your profile's stars tab - any depth, and only a slash nests
• A pinned rail of every list beside each list's page, with the list you are reading opened into view
• A filter box that narrows the rail and opens just the folders holding a match
• A list named exactly like a folder (parent next to parent/child) becomes that folder's own clickable row
• Follows GitHub's name sorting (A–Z / Z–A) and your GitHub theme
