docs: describe repo info path keys and structure metrics

eslam-reda-div · eslam-reda-div · commit c9973b4d3f0c · 2026-02-23T14:23:20.000+02:00
Document the newly added repo info capabilities, including category keys and path-oriented key definitions, and describe --path-format behavior for path outputs.

Also update git repo structure documentation to cover newly reported maxima and aggregate keyvalue/nul fields so command behavior and output keys are fully specified for users and scripts.
