Add GitHub App authentication support - #154
Merged

Conversation
Add app_id and private_key fields to Source struct. Refactor GitHubClient to use hasAuth/tokenFunc instead of raw accessToken string, enabling both PAT and GitHub App auth. Auto-discovers installation ID via Apps.FindRepositoryInstallation.
Tests cover: - Conflicting auth configuration (token + app creds) - Incomplete app credentials (app_id without private_key and vice versa) - Successful installation discovery and token-authenticated GraphQL - Installation not found (404) - Invalid private key
Concourse credential managers interpolate all values as strings. Use a FlexInt64 type that unmarshals from both JSON numbers and quoted numeric strings.
- Extract normalizeURL helper to remove 3x duplicated URL normalization in appInstallationClient - Return error instead of silently ignoring url.Parse failure - Add tests for FlexInt64 unmarshaling from JSON string (the actual credential-manager scenario that broke in production)

There was a problem hiding this comment.
LGTM - I want to bump go-github to v88 to match the new dependency and just for the sake of staying closer to the latest version. I'll do that in another PR. There are some other minor nits as well but I'll fix those in my PR.
I have not manually tested this with a github app. I am trusting that you have.

Motivation
Some organizations forbid the use of personal access tokens, which makes this resource unusable in those environments. This PR adds GitHub App authentication as an alternative to personal access tokens.
Changes
Adds
app_idandprivate_keyas source configuration options. When provided, the resource authenticates as a GitHub App installation:owner/repositoryExample configuration
Notes
app_idaccepts both numeric and string values (credential managers like Vault/CredHub interpolate everything as strings)access_token- providing both is a validation erroraccess_tokenFixes #124
