--genkey option creation

[Lvceo]

A --genkey option should be a plus to avoid asking user to create their Private Key manually with

$ openssl rand -hex 32

At start a dotfile must be searched if not existing, then a Warning must be written (if not Error instead).
When private key is created and stored in dotfile, then dotfile should be verified to be owned by the user and file mode must be 600.

Since a user of command line tool may be expected to generate their own keys using openssl, I am inclined to keep this option out of nostr console. This will simplify the tool and keep key generation separate from console - the user will know its their job to create and save their keys.

I understand your position, but for the sake of simplicity, having to just use one tool instead of several is a plus in terms of user experience, IMHO (think of new comers). Theses keys could be stored in a ad-hoc .dotdir for nostr_console. Providing a single point of entry.
