   Makes sense as a follow-up, but it's not as simple as it sounds today: 
`DaemonInfo`/`DaemonRegistry` don't track a version at all right now -- the 
daemon never sends one when it registers itself (`Server.java`), and the 
registry is a positional binary format (`writeUTF`/`writeInt` in fixed order, 
no schema versioning), so adding a field there is an on-disk format change that 
affects compatibility with daemons already running from older mvnd builds.
   
   I'd rather not fold that into this PR, which is a narrow, already-tested 
fix. Happy to open a follow-up issue for "surface the running daemon's version 
(e.g. as a column in `--status`)" if that's the right place for it -- let me 
know and I'll file it.
