fix(#520): register package-identity.cjs in inventory (regression from #516) (#521)

#516 added get-shit-done/bin/lib/package-identity.cjs without regenerating
the inventory, breaking inventory-manifest-sync and inventory-counts on next.
Regenerate docs/INVENTORY-MANIFEST.json and bump docs/INVENTORY.md
CLI-module count 76 -> 77 with the new row.
