[Medium risk] Refactors bundle artifact inspection to use standardized helpers.

The PR appears safe to merge with its stacked performance follow-up.

Summary

The PR changes local bundle inspection to read metadata directly from the archive rather than extracting an OCI workspace, and adds coverage for Zarf multi-document parsing and migrations.

• No PR-file changes were made since the previous review.
• The previously noted repeated-decompression cost is addressed in the higher PR in the stack.
