Dependency Bump Evaluation

Version change: docker/setup-buildx-action v4.1.0 → v4.2.0 (minor)

Changes:

• Internal dependency bumps only: @actions/core, @docker/actions-toolkit, @sigstore/core, @sigstore/verify, js-yaml, sigstore, tmp, undici, vite
• Build config tweak: preserve names in esbuild bundle
• No changes to the action's public API, inputs, or outputs

Breaking changes: None

Security concerns: None — includes routine updates to sigstore and undici (internal to the action)

Impact on codebase: The action is used with default settings (no custom inputs) in .github/workflows/build.yaml:39. Zero codebase impact.

CI status: Build, lint, and test checks are still in progress. Verify they pass before merging.

Recommendation: SAFE TO MERGE
