rewrite objectiveai-cli in Rust #141
Description
for some reason a lot of AI CLI tools use Node/Bun and it uses a lot of memory and it's slow,
our CLI should be in Rust so that coding agents running in an inefficient CLI don't compound this inefficiency by using yet another inefficient CLI within their CLI.
since function invention and publishing now happens on the API server, the CLI is basically just going to be a thin client now so this shouldn't be hard and we already have a Rust SDK
