Experiment with Bun bundling for distributing the CLI as a single-file executable

[vladfrangu]

After the meeting with @netmilk about the CLI, we should try using Bun to build a single-file executable of the CLI that can then be distributed ("eliminating" the requirement of having node installed/tagged along to run the CLI)

Initial testing shows that we might need oclif's help, as they rely heavily on finding the package.json, so that might need tweaking (or a replacement of CLI frameworks).
