Create a PR using Bootstrap::GitHubUtils

Use the in-repo helper to create PRs via the GitHub REST API without relying on gh.

Preconditions

• You have a branch pushed to origin (e.g. feature/my-branch).
• A GitHub token exists in /work/.git-credentials (or pass an explicit path to create_pull_request).

Create the PR

From the repo root (/work/bootstrap-qcow2 when live-bound):

./bin/bq2 github-pr-create --title "PR title" --head feature/my-branch --body-file pr-body.md

Notes

• If the API call fails, the helper raises with the HTTP status/body to copy into debugging output.
• Updating an existing PR body/title requires a PATCH request; reuse the same token/headers pattern (see src/github_utils.cr).
• Pass --repo owner/name when running outside a git checkout (e.g., staged snapshots) and inference fails.
• Defaults to /work/.git-credentials when present (override with --credentials).
