Hi, uutils mainteners stat have some problems like printf, with the --printf, that is my tries of all previous isses and some work against stat --printf

Research direction
Start in src/uu/stat/src/stat.rs at the reported locations around lines 113, 587, 669, 694, and 719. Reproduce the failures with the listed stat --printf formats, then trace how large widths and precisions are handled. Done means these inputs no longer panic and retain appropriate stat --printf behavior.
