[BUG] Readme states traces are implemented but code says otherwise

[grantkl]

return fmt.Errorf("traces command is under development - use monitors, dashboards, slos, or incidents instead")

[platinummonkey]

this isn't available yet, just updated the README a moment ago, good timing.

[grantkl]

Thanks, is there a rough eta on when it will be supported?

[platinummonkey]

I'll try to find that out

@platinummonkey I'll drop the superpowers design and plan doc to be consistent with the repo before I mark this as ready, but I thought it was more useful to have it for now while this is in flight.
