ci: pin third-party actions to full commit SHAs and declare minimal workflow permissions (E00-S05-T01)

- actions/checkout pinned to 11bd71901bbe5b1630ceea73d27597364c9af683 (v4.2.2)

- workflow-level permissions: contents: read (the pipeline only reads the repo)
- no floating @v4 tags remain anywhere in the workflow
