PR Summary

• Adjustments to configuration.nix
  These changes include the incorporation of a new yabai.nix file within the imports list and setting the ApplePressAndHoldEnabled feature to false in the defaults section. This will refine the user experience and performance of the system.

• New yabai.nix File Creation
  This file is responsible for the configuration of yabai for each user, enabling them to execute it with elevated privileges (sudo) without needing a password. This increases convenience and efficiency in user operations.

• Upgrades to frontend-dev.nix
  An additional line was added to ensure npm binaries (program's executable files) are readily accessible while using the interactive Fish shell, which enhances the software development process's smoothness.

• Amendments to skhd.nix
  The commented source path for skhd has been updated and the window handling script has been optimized. This optimization changes how WINDOW_ID is determined and eliminates superfluous code. The overall system functionality and efficiency are improved as a result.

• Enhancements to starship.nix
  The improvements consist of the Starship prompt being enabled and the activation of the git_state features. These changes provide users with a better interface and more functionality.

• Changes in yabai.nix
  The source path for yabai has been removed, giving us a cleaner configuration setup, without the need for a direct file reference, which simplifies the system and minimizes possible errors.
