Connecting GitHub required hand-registering an OAuth app and pasting a client
id + secret — friction, and an open-source panel can't ship a secret anyway.
Now an admin sets it up in one click.
- backend: build_github_app_manifest / complete_github_app_manifest — hand
GitHub an app manifest, convert the returned code into credentials stored
locally (client id/secret in settings; PEM + webhook secret encrypted). No
shared secret in the repo or build.
- connect flow: when an app slug exists, generate_github_authorize_url points at
the app's install screen (grants repos + authorizes in one hop); repositories
are listed per-installation since GitHub Apps don't use /user/repos.
- get_github_config surfaces provider_kind/app_slug/app_name/install_url.
- routes: GET/POST /source-connections/admin/github/app-manifest[/complete].
- frontend: Settings -> Connections leads with "Set up in one click" (auto-POSTs
the manifest form to github.com); a new /connections/github-app/callback page
finishes setup and chains into connect. Manual OAuth app moves under
"Advanced". 7 proving tests (manifest shape, conversion+storage, install-url
routing, app-mode repo listing); ratchet 2498->2505.
