Rust Coreutils 0.12 vs GNU 9.12: almost everything works the same, starting a process costs nearly 3x more

I measured Rust Coreutils (uutils) 0.12 against GNU coreutils 9.12 in containers with limits: the full GNU test suite, 157 commands with their output compared byte for byte, and process start-up.

• uutils is slower in 91 of 157 cells.
• It takes 2.8x longer to launch 5,000 processes.
• mv between disks loses the timestamps.

Where each one wins, the full command matrix, and whether it's ready to replace GNU on a real box — in the write-up.
