Ability to manually assign a name for connections not defined in ~/.ssh/config

[json1c]

First of all — thanks a lot for this handy tool, it's incredibly useful!

I wanted to suggest a small but practical feature:

Currently, the connection "Name" field is only available if it's explicitly defined in ~/.ssh/config via the Host entry. However, when connecting directly using ssh user@host -p 2222 or similar commands (i.e. not via a predefined config), there's no way to assign a meaningful name to that connection — and the interactive history view shows an empty name.

When no name is available, prompt the user to optionally enter a name before saving the connection to ~/.ggh/history.json.

Something like:
Enter name for this server (optional, press Enter to skip):

This would allow users to more easily distinguish frequently used connections in history, even if they're not stored in ~/.ssh/config.

Alternatively or additionally, supporting custom names via a .ggh/config.json file could be a nice enhancement.

Let me know if you'd be open to a PR — I’d be happy to help implement this
