Function github_public_api_token

crates/jcode-base/src/github.rs:21–34

Resolve a GitHub token for authenticated public API access. Order: `GH_TOKEN`/`GITHUB_TOKEN` env vars, then a `gh auth token` subprocess lookup cached once per process (including a cached miss, so the subprocess is spawned at most once). Returns `None` when no token is available; callers should proceed unauthenticated in that case. Only send this token to `api.github.com` public read endpoints.
