…e column detection method cleaner.
…w them to be exposed for things like pmstat Used Claude Code to generate this.

At the moment,
pmstaton macOS is quite lean on what it can show because some metrics are not available (yet).this change aims to add some metrics but also modify
pmstatso that it (optionally) hides columns that are not available.I held several sessions with Claude Code to get here because it's certainly better at C than I am... After some back and forth I narrowed in on the
-Cand--compactmode forpmstatwhich seemed to not conflict with any other pm-tool that Claude looked at (and my fuzzy memory). I elected to make this compact mode optional, and not default, just to maintain backwards compatibility. There's certainly a 'brain freeze' moment when one runspmstatand sees a lot of columns missing, so I wondered if it was better to maintain the original layout (with missing metrics) as the default for us old folks...There may be some other metrics I can get for macOS, will do that in a separate set of sessions but thought I'd start here to get some feedback on it (I'll pass that on to Claude. :-D )
I had some earlier CI build failures on my fork, but not sure if that was just when I made the fork, so I have rebased my branch from this morning and lets see what happens.
This goes towards #2303
