Advances #1.

RepositoryInspector.diff() fences a diff snapshot by comparing initial/final git rev-parse HEAD strings, but it does not validate either sample as a full Git object ID. Stable malformed Git/mock output can therefore be accepted as repository identity while diff evidence is projected.

Acceptance:

deterministic RED for stable malformed diff HEAD object IDs;
accept canonical 40- and 64-hex object IDs;
validate both initial and final HEAD samples before identity comparison;
preserve existing identity-race, working-tree-race, structured numstat, bounds, and allowed-root semantics;
focused tests, registry compatibility, full nix flake check, generated package builds, exact-head protected merge.
