  Fixed packages:
     ✓  [update] ws 8.18.2 → >=8.21.0

  Risk assessment:
     ▲ high  [override] js-yaml >=4.2.0: major version bump 3.14.2 → 4.2.0, 1 parent(s) may break

  Run with --auto-fix to fix: js-yaml
    (or --apply-overrides for: js-yaml)

  ⚠  DRY RUN — no changes were made. Run without --dry-run to apply.

How this works

1. Analyses all open Dependabot alerts
2. Applies each fix individually with build verification
3. Rolls back any fix that breaks the build
4. Only passing fixes are included in this PR

Review checklist

• Check that no breaking changes were introduced
• Verify rolled-back packages are investigated separately
• Run tests locally if concerned about specific packages
