v0.5.3 — Fix resource swapper, add Husky, remove uuid

Fix three Electron 12→42 protocol migration bugs in the resource swapper:
register protocol on the app session instead of default, generate valid
URLs from Windows paths, and prevent non-swapped krunker.io requests from
being cancelled. Swapper now rescans on page refresh to pick up file changes.

Add Husky pre-commit hook to run ESLint. Remove unused uuid dependency.
Update README with lint script, husky, and swapper improvements.
