fix(ci): don't cancel/rerun PR CI when an unrelated label is added

[ulixius9]

Problem

Adding any label to a PR cancels the in-flight CI run and restarts it. This makes sense for safe to test (the label that gates CI), but not for labels like to release — there's no reason to cancel and rerun the whole pipeline.

Root cause

Every PR-CI workflow triggers on pull_request_target with types: [..., labeled] and used:

concurrency:
  group: <name>-${{ github.event.pull_request.number || github.run_id }}
  cancel-in-progress: true

Adding a label fires a labeled event → the new run joins the same concurrency group → cancel-in-progress: true kills the running build. And because the PR already carries safe to test (that's why CI was running), the new run's Verify PR labels step passes and it reruns everything.

Fix

Two parts per workflow, both gated on the safe to test label:

1. Concurrency — cancel-in-progress is now an expression that stays false for labeled events unless the added label is safe to test, so an unrelated label no longer cancels the running build:

   cancel-in-progress: ${{ github.event_name != 'pull_request_target' || github.event.action != 'labeled' || github.event.label.name == 'safe to test' }}

2. Gateway job if — the same clause, so an unrelated label doesn't spawn a duplicate run. Downstream needs: jobs skip automatically, exactly as they already do for draft PRs.

push / merge_group / workflow_dispatch are unaffected via the event_name != 'pull_request_target' clause.

Behavior after

• Add safe to test → CI runs (and cancel-on-new-push still works) — unchanged.
• Add to release / any other label → the running CI is not cancelled and no duplicate run starts.

Scope

• 19 pull_request_target + labeled workflows updated (ui-checkstyle.yml already had the job gate, so it only needed the concurrency line).
• Left untouched: team-labeler.yml and auto-cherry-pick-labeled-prs.yaml (these intentionally act on labels), and the *-e2e-skip.yml shims (no concurrency).
• All 19 files validated as parseable YAML.

❌ PR checklist incomplete

This PR cannot be merged until the following are addressed on its linked issue:

• No GitHub issue is linked. Add a closing reference such as Fixes #12345 to the PR description (accepted keywords: Fixes, Closes, Resolves).

The fields live on the linked issue in the Shipping project (open the issue → right sidebar → Projects). After you set them, re-run this check (or push a commit) — issue/project changes do not re-trigger it automatically.

Maintainers can bypass this check by adding the skip-pr-checks label.

Pull request overview

This PR updates OpenMetadata’s PR CI GitHub Actions workflows to prevent in-flight CI runs from being cancelled/restarted when unrelated labels are added to a PR, while preserving the intended behavior for the safe to test gating label.

Changes:

• Makes workflow-level concurrency.cancel-in-progress conditional so pull_request_target labeled events only cancel in-progress runs when the added label is safe to test.
• Adds/updates an equivalent “gateway job” if: condition so unrelated label events don’t spawn duplicate workflow runs (downstream needs: jobs remain skipped as usual).
• Applies the pattern across 19 affected PR-CI workflows (leaving label-driven automation workflows untouched, per PR description).
