Dependency Bump Evaluation

Version change: docker/setup-buildx-action v4.2.0 → v4.3.0 (minor)

Changes:

• Internal dependency bumps only: @docker/actions-toolkit 0.92.0→0.95.0, brace-expansion 1.1.13→1.1.18, js-yaml 5.2.0→5.3.0, postcss 8.5.10→8.5.25, undici 6.27.0→6.28.0
• No feature additions or behavioral changes in the action itself

Breaking changes: None

Security concerns: None — all updates are routine internal dependency bumps within the GitHub Action

Impact on codebase: Minimal. The change updates a single line in .github/workflows/build.yaml (action SHA pin + version comment). No project source code is affected.

CI status: build passed; generate, lint, test, test-e2e still in progress at time of evaluation

Recommendation: SAFE TO MERGE (once CI is green)

Notes: Auto-approval skipped because the PR author is scality-renovate[bot], not dependabot[bot].
