No Changes Needed: Tig to Gitui Replacement Analysis

I've analyzed the codebase to implement the requested replacement of Tig with Gitui, but no immediate code changes were identified. The analysis was inconclusive as I couldn't locate where Tig is currently configured in the dotfiles repository.

Next Steps:

• Could you please provide more details about where Tig is currently configured?
• Specifically looking for configuration files or installation scripts that reference Tig

Once I have this additional context, I can properly implement the replacement with Gitui as requested.
