Load/extend multiple profiles

[strayer]

I'd like to be able to extend multiple profiles, e.g. have a profile for cargo projects, a profile for Python projects and a profile for Claude Code. Then I could run nono run --profile claude-code --profile cargo and by that only load the profiles I specifically need for the project I'm working on. The same might make sense for the extends property in profiles themselves to abstract fine-grained permissions.

As far as I can see both is currently not possible, right? I'd have to define multiple profiles that duplicate configuration a lot, or build my own template-based system for setting up profiles.
