Research direction

Start by reproducing the command ./seq -f "%.65536f" 1 10, then inspect src/uucore/src/lib/features/format/num_format.rs around line 373 and trace how the format argument is handled. Done means the command no longer panics and its behavior matches the intended seq formatting behavior; run the relevant seq tests afterward.
