# @brief Installs dependencies, clones the Install Doctor repository, and then starts Chezmoi
# @description
#   This script ensures Chezmoi, Glow, and Gum are installed. It also includes logging functions for styled logging.
#   After dependencies are installed, it adds the necessary files from https://gitlab.com/megabyte-labs/install.doctor.git into
#   ~/.local/share/chezmoi. Finally, it begins the TUI experience by displaying styled documentation, prompts, and finishes
#   by calling the appropriate Chezmoi commands.
