- resolve the GitHub App by a stable identifier during installation
callbacks so installing and re-installing keeps working over the
full lifetime of the App
- verify the installation id received from the callback against the
GitHub API before persisting it
- support re-installing an already configured GitHub App instead of
blocking it
- require an authenticated session and rate limit the setup callback
routes
- extend manifest setup state validity to match GitHub's manifest
code lifetime
Adds feature coverage for the GitHub App setup and installation
callbacks.
