workshop switch and "default" workshop

[Perfect5th]

Maybe this is already a feature and I just missed it, and admittedly this is a very minor thing and just a "nice-to-have".

In a multi-workshop environment (multiple yamls under .workshop) it would be nice to have a way to "switch" between them and not have to specify the workshop name for every command.

e.g., something like

$ workshop list
WORKSHOP  STATUS  NOTES
noble     Ready   default
resolute  Ready   -

$ workshop run myaction
# runs in 'noble'

$ workshop switch resolute
resolute is now the default workshop

$ workshop list
WORKSHOP  STATUS  NOTES
noble     Ready   -
resolute  Ready   default

$ workshop run myaction
# runs in 'resolute'

Agreed something like this could be useful. In my opinion it should work like a python venv, i.e. applies to the current shell session but isn't a global config value like lxc switch is.
