…t of #1795)

The remaining changes from #1795, adapted to the release/** RC model:

• Remove the GitLab bridge: build_validation.yml (repo mirror + .gitlab-ci.yml trigger) and mirror_repo.sh — superseded by the native ci.yml.
• Add trigger-gitlab-nspect to ci.yml: on a push to a release/** branch (a PR merged into release/<x.y.z>), trigger the nixl-ci GitLab pipeline (PIPELINE_TYPE=rc) to run the wheel scan + nSpect registration (NSPECT-WO64-8O3P) against the wheels just uploaded to Artifactory. Runs on the gitlab_ci_runners group (internal reach); WHEEL_VERSION comes from the version job; NIXL_CI_REF selects the nixl-ci branch (defaults to main). (Nmailhot/nixl release pipeline #1795 gated this on v*-rc tags; re-gated for the release/** model.)

📝 Walkthrough

Walkthrough

The PR removes the build_validation.yml workflow and the mirror_repo.sh Bash script (both handling GitLab mirroring). It adds a new trigger-gitlab-nspect job in ci.yml that runs only on release/** branches, waits for wheel uploads to finish, then POSTs a GitLab pipeline trigger with nSpect registration and wheel-scan variables.

Changes

GitLab CI Infrastructure Replacement

Layer / File(s)	Summary
Remove GitLab mirror script and validation workflow .github/workflows/mirror_repo.sh, .github/workflows/build_validation.yml	Deletes the polling mirror-update Bash script and the entire build_validation workflow (mirror-to-GitLab job and GitLab CI trigger job).
Add trigger-gitlab-nspect release job .github/workflows/ci.yml	Adds a release-branch-only job that depends on version, upload-x86-wheels, and upload-arm-wheels; securely stores the GitLab token in a temp file; POSTs a multipart trigger request with NSPECT_ID, WHEEL_VERSION, RC_TAG, ENABLE_WHEEL_SCAN, and other variables; extracts PIPELINE_ID/PIPELINE_URL via jq; errors if no pipeline ID; writes a summary table to GITHUB_STEP_SUMMARY.

Poem

🐇 Hop hop, the mirror is gone,
No more polling from dusk until dawn.
A curl to GitLab, nSpect in sight,
Wheels get scanned in the release-branch night.
One clean trigger, the rabbit says "Right!" 🎉
