hc: keep updateNodeColors quiet and out of the HC Panel

It runs on every hip load and at startup, so its status message was
always said when you opened a file rather than when you asked for
anything -- and now that an unchanged scene writes nothing, it mostly
said "0 nodes". The count is still returned for callers that want it.

Dropping the @command takes it back out of the HC Panel too. It is an
automatic maintenance pass, not something to reach for from the command
list; the main menu item stays for the rare manual run.
