Description

pretty_size and pretty_duration pick the unit before rounding, so values just under a boundary come out in the wrong unit once they're formatted.

• pretty_size(1024 * 1024 - 1) gives 1024k instead of 1.0m
• pretty_duration(0.9996) gives 1000ms instead of 1.00s
• pretty_duration(9.996) gives 10.00s instead of 10.0s
• pretty_duration(99.96) gives 100.0s instead of 100s

These show up in the console flow list and in the dumper output. The fix compares the rounded value against the limit, so the unit and precision match what actually gets printed. I also swept a few million sizes and durations around the boundaries to make sure none of the odd outputs are left and pretty_size still stays at 5 characters or less.

Checklist

• I have updated tests where applicable.
• I have added an entry to the CHANGELOG.
