Cross-library comparison

Availability

Component files exist (ui/views/cross_library.py, frontend/src/components/charts/CrossLibraryHex.tsx) but neither is currently wired into the active SPA layout or the run.py Marimo notebook. The SPA does ship HexComparison / HexOverlay for dump-vs-dump comparison inside a single library.

Side-by-side hex panels for the same secret type across two or more libraries. Reveals how different implementations serialize the same cryptographic primitive.

To render it today, import the component into a custom Marimo cell or extend the SPA workspace.
