feat: optional gh_token to install private-org deps in CI

[JarbasAl]

Adds an optional gh_token secret to the reusable build-tests and coverage workflows. When a caller passes it, git is configured (insteadOf) to authenticate clones of PRIVATE org dependencies during pre_install_pip. No-op when unset, so all existing callers are unaffected.

Use case: a public repo whose CI installs an unpublished/private sibling package from a branch ref.

Summary by CodeRabbit

• New Features
  • Added optional support for authenticated installs of private GitHub dependencies in CI workflows.
  • Workflows can now accept a token to help package installation succeed when pre-install steps pull from private repositories.
  • The token-based setup only runs when custom pre-install commands are provided, leaving standard builds unchanged.

Warning

Review limit reached

@JarbasAl, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 4 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

Both build-tests and coverage workflows add an optional gh_token secret and a conditional step that configures git URL rewriting before pre_install_pip runs.

Changes

Private dependency Git authentication

Layer / File(s)	Summary
Secret interface .github/workflows/build-tests.yml, .github/workflows/coverage.yml	Both workflows declare an optional workflow_call secret named gh_token for private dependency authentication during pre_install_pip.
Conditional git auth step .github/workflows/build-tests.yml, .github/workflows/coverage.yml	Both workflows add a step, gated by pre_install_pip, that rewrites https://github.com/ clone URLs to include the token when the secret is present.

Poem

A bunny hops through YAML in the night,
With token-tipped whiskers, all set right.
Private clones now roll along,
While pre_install_pip sings its song.

Inline comments:
In @.github/workflows/build-tests.yml:
- Around line 91-102: The git authentication step in the workflow is leaving a
global token rewrite behind in `~/.gitconfig`, which can expose `GH_DEP_TOKEN`
to later steps. Update the `Authenticate git for private dependencies` step so
the `git config --global url."https://x-access-token:...".insteadOf` setting is
only applied for the `pre_install_pip` phase, or add a following cleanup step
with `always()` to remove that global config immediately after. Keep the fix
localized around the existing `Authenticate git for private dependencies` step.

In @.github/workflows/coverage.yml:
- Around line 128-139: The git authentication rewrite in the private
dependencies step leaves a global `insteadOf` rule behind, which can leak into
later operations such as the Pages deploy push. Update the workflow around the
Authenticate git for private dependencies step to add an immediate cleanup using
the same git config key so the token rewrite is removed right after pre-install;
use the existing authenticate step name and the git config
`url."https://x-access-token:${GH_DEP_TOKEN}`@github.com/`".insteadOf` setting as
the identifiers to locate and reverse.
