Deduplicate files that already exist in base layer
Metadata
Current evaluation
Overlay builds still prime copies of files already present in the base layer, increasing image size; the request remains open with only an autogenerated Jira-ticket comment.
Suggested action: keep open
Reason: The inefficiency remains applicable to overlay builds, particularly when chisel slices defeat package-cutoff deduplication. Current overlay prime handling uses the base-layer path only to clean dangling whiteouts, and repository searches found no deduplication implementation or resolving fix; however, defining safe equality and overlay semantics will require design and test work.

Issue body
### What needs to get done
If using overlays, avoid priming files that already exist in the base layer.
### Why it needs to get done
File duplication across layer results in inefficient images. Using package cutoff alone is not enough if chisel slices are being used.
