CLI: I'd like to see a CLI version of `alma` that allows it to be launched from the terminal.

One bit of a hassle is that if you want to load a custom workspace, you have to create a new conversation and then select a directory from the workspace—and Finder is really clunky.

I’d like Alma to automatically create a new session when launched from the CLI and set the current directory as the workspace (just like `code` or `zed`).
