In format_age(), change %dm → %dmin (and similar in all branches).
Why needed:
"42m" is ambiguous (minutes? meters? months?)
"42min" is immediately clear and readable
Matches common conventions (e.g. "5d 3h 42min 17s" in many tools)
Tiny change, zero performance impact, big UX improvement
Before:
5d 3h 42m 17s
After:
5d 3h 42min 17s
Please apply consistently across all format branches. Thanks!
