Development environment only — nothing in the app or the build depends on either.

• gh in the image, which is what opens pull requests from inside the container.
• Anthropic.claude-code in the devcontainer extension list.
• Restores the trailing newline on devcontainer.json, which an editor had stripped.

Heads-up: CI will fail here until devkitPro is reachable

pr.yml rebuilds the image from scratch whenever a PR touches docker/*Dockerfile, rather than pulling the published one — deliberately, so a PR changing the image definition can't silently test against the old toolchain.

A scratch build runs dkp-pacman -Sy, and pkg.devkitpro.org is currently behind a Cloudflare block returning HTTP 403 on dkp-linux.db / dkp-libs.db. Reproducible outside CI:

$ curl -so /dev/null -w '%{http_code}\n' https://pkg.devkitpro.org/dkp-linux.db
403
$ curl -s https://pkg.devkitpro.org/dkp-linux.db | grep -o '<title>[^<]*</title>'
<title>Attention Required! | Cloudflare</title>

Nothing in this PR causes that — it just takes the code path that reaches for it. Re-run the Build job once devkitPro's mirror is serving again.

Split out of #22 for exactly this reason: that PR carries the app changes and shouldn't be blocked on a third-party outage.
