Support for the fish shell

[alec-c4]

Hey!
Do you plan to add support for other shells, like fish? I believe I can add it, but

1. I'd like to propose to change syntax from eval "$(dip console)" to something like eval "$(dip init fish)" similar to mise, starship etc
2. to avoid any issues in future releases, I'd like to ask you, is there other places related to shell integration or only in lib/dip/commands/console.rb?

Hi!
Thanks for reaching out and for your interest in adding support for fish shell!

• I personally don’t use fish, so I hadn’t planned to add support for it, but I’m open to contributions.
• I’m fine with changing the syntax to something like eval "$(dip init fish)", as it aligns with tools like mise and starship. However, we’ll need to ensure backward compatibility for users who still rely on the current eval "$(dip console)" syntax.
• As far as I can tell, the shell integration is indeed only handled in lib/dip/commands/console.rb.

Feel free to work on this and submit a PR!
