Send Feedback now actually works. The GitHub sign-in flow was quietly broken end-to-end since
it shipped in v1.4.0 — a wrong OAuth parameter meant sign-in always failed, and even after that was
fixed, posting itself needed a permission Narraity never requested. Both are fixed: sign in with
your GitHub account and post a bug report or suggestion straight to the project's Discussions, for
real. If you tried Send Feedback before and it didn't work, sign in again to pick up the fix.
The device code doesn't vanish anymore. Signing in used to open your browser immediately,
which could bury the one-time code you need to enter before you'd had a chance to read it. It's
now copied to your clipboard automatically and stays on screen a moment longer, so paste it in
even if the window ends up behind the browser.
