Should we use only a Rust CLI for everything `buddy`?

[ubiratansoares]

Right now, we have two wrappers around limactl driving vm/buddy related tasks:

• the justfile
• the Rust CLI for credentials (which is invoked from with the justfile via cargo)

I was wondering wheter we should implement existing tasks on top of the Rust CLI only. That would allow removing just as a required dependency to get started and would gives us room for a richer CLI experience

# cargo already required, no changes here
cargo install --git https://github.com/rustfoundation/buddy

# some replacements as they are
buddy create
buddy start
buddy login

# filter the service using a CLI argument
buddy login --service fastly

# flags
buddy logout --all

# for https://github.com/rustfoundation/buddy/issues/44 
# we could render a templated `provision.sh` to drive the vm creation      
buddy create --harness claude
buddy recreate --add-tool zig

# etc
