Proper GitHub

Replaces GitHub's pull request file viewer with Monaco Editor — faster diffs, inline comments, and a cleaner review experience.

Detailed description:

Proper GitHub upgrades the pull request experience on GitHub with a professional code review
interface.

When you open a pull request, the extension replaces GitHub's native diff viewer with Monaco
Editor — the same editor that powers VS Code. Everything else on GitHub stays untouched.

What you get:

- Side-by-side and inline diffs powered by Monaco Editor with full syntax highlighting
- A file explorer with folder tree view, search, and file type icons
- Inline code suggestions — select lines, edit directly in the diff, and submit as a suggestion
- Comment and review system with markdown preview and thread resolution
- Image diffs with 2-up, swipe, and onion skin modes
- CI status and review state at a glance in a unified toolbar
- Commit-by-commit browsing or full diff view
- Keyboard navigation between files
- Instant file switching with background prefetching

The extension works entirely in your browser. It communicates directly with GitHub's API using
your Personal Access Token — no data is sent to any external server. Fully open source under the
MIT license.

Requires a GitHub Personal Access Token with repo scope to access the API.
