t1901: extend structure metric coverage and portability
Expand t1901 to cover additional structure metrics emitted by git repo structure, including maxima and aggregate keyvalue/nul checks. The test now validates both human-oriented table content and machine-readable fields for the extended metric set. Also make expectations more portable across hash algorithms and platforms by avoiding brittle assumptions. This includes wc output quirks on BSD/macOS and hash-format- sensitive expectations.
