Issue (Important): actions/checkout@v5 requires Node.js 24 and may break on self-hosted runners

Context:
This PR bumps actions/checkout from v4 to v5 across multiple workflows (.github/workflows/auto-release.yml, pre-commit.yml, release.yml, test.yml, ty.yml). Checkout v5 runs on Node.js 24. If any of your self-hosted runner pools (e.g., labels ubuntu-latest-8, ubuntu-latest-16, ubuntu-latest-32) aren’t updated to a runner version that supports Node 24, the checkout step will fail to initialize at runtime, causing CI failures.

Why this matters:

• It’s a runtime compatibility risk on self-hosted runners that lag behind GitHub’s runner updates.
• Failures would occur immediately when the action loads, blocking all dependent jobs.

Actionable recommendation:

• Verify that all self-hosted runner groups used by these jobs support Node 24.
• If not yet upgraded, keep actions/checkout at v4 for those specific jobs until the runner pools are updated.
• After verification/upgrade, proceed with v5.

Example targeted rollback suggestions (apply only where runners aren’t Node 24–ready):

Auto Release:

      - uses: actions/checkout@v4
        with:
          fetch-depth: 0

Pre-commit:

        uses: actions/checkout@v4

Release (build job):

      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
          ref: ${{ inputs.release-tag || github.event.pull_request.head.ref || github.ref }}

Release (release job):

      - uses: actions/checkout@v4

Tests – unit-tests job:

      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
          ref: ${{ github.event.pull_request.head.sha }}

Tests – codemod-tests job:

      - uses: actions/checkout@v4
        with:
          ref: ${{ github.event.pull_request.head.sha }}

Tests – integration-tests job:

      - uses: actions/checkout@v4
        with:
          ref: ${{ github.event.pull_request.head.sha }}

Once all self-hosted runners are confirmed to support Node 24, you can safely move each job back to actions/checkout@v5.
