Poem

🐰 With concurrency blocks now in place,
No workflows will overlap or race,
Main branch runs safe, others compressed,
GitHub's queue gets a well-deserved rest! ✨

Greptile Summary

This PR adds a concurrency block to all 11 GitHub Actions workflow files, cancelling in-progress workflow runs when new commits are pushed to a PR branch, while preserving runs on main (and scheduled runs, which also target main). This is a standard GitHub Actions optimization that avoids wasting CI resources on stale runs.

• All 11 workflow files receive the same consistent 4-line concurrency addition with group: ${{ github.workflow }}-${{ github.ref }} and cancel-in-progress: ${{ github.ref != 'refs/heads/main' }}
• The codeql-analysis.yml workflow also has a weekly scheduled trigger (cron: '00 6 * * 1'); since scheduled events run against refs/heads/main, cancel-in-progress will correctly evaluate to false for those runs, preventing security scans from being prematurely cancelled
• Workflows that only trigger on pull_request (e.g. check_changelog.yml, check_pr_size.yml) will have cancel-in-progress always evaluate to true, which is the expected and correct behavior since PRs never have github.ref == refs/heads/main
• Pushes to release-** branches will also have cancel-in-progress: true — this is intentional and consistent with wanting cancellation everywhere except main

Confidence Score: 5/5

• This PR is safe to merge — changes are purely additive CI configuration with no impact on application code.
• The changes are identical, low-risk YAML additions across 11 workflow files. The concurrency pattern used is a well-established GitHub Actions best practice. The cancel-in-progress guard correctly preserves runs on main, including both push-triggered and scheduled runs (e.g. CodeQL). No application logic is touched.
• No files require special attention.

Important Files Changed

Filename	Overview
.github/workflows/backend_checks.yml	Adds standard concurrency block to cancel in-progress runs on new commits, protecting main branch from cancellation.
.github/workflows/check_changelog.yml	Adds concurrency block with cancel-in-progress logic; note this workflow only triggers on pull_request so cancel-in-progress will always be true (PRs never have ref == refs/heads/main).
.github/workflows/check_pr_size.yml	Adds concurrency block; minor formatting note — no blank line before the concurrency key unlike other files, but valid YAML.
.github/workflows/chromatic.yml	Adds standard concurrency block, consistent with other workflow files.
.github/workflows/cli_checks.yml	Adds standard concurrency block, consistent with other workflow files.
.github/workflows/codeql-analysis.yml	Adds concurrency block to a workflow that also has a scheduled trigger (weekly cron). Scheduled runs fire on the default branch (main), so cancel-in-progress will be false — preventing overlapping security scans from interfering with each other. Behavior is correct.
.github/workflows/cypress_admin-ui.yml	Adds standard concurrency block, consistent with other workflow files.
.github/workflows/cypress_fides-js.yml	Adds standard concurrency block, consistent with other workflow files.
.github/workflows/cypress_privacy-center.yml	Adds standard concurrency block, consistent with other workflow files.
.github/workflows/frontend_checks.yml	Adds standard concurrency block, consistent with other workflow files.
.github/workflows/static_checks.yml	Adds standard concurrency block, consistent with other workflow files.
