# Installs a file or directory from a source path to a destination path within the user's home directory.
# This function first removes any existing item at the destination and ensures its parent directories exist.

# Arguments:
#   $1 (source_path):       The path to the source file or directory, relative to the current working directory ($CWD).
#   $2 (dest_path):         The desired destination path, relative to the user's home directory ($HOME).
#   $3 (copy_mode_flag):    Optional. If '1', performs a full recursive copy (`cp -Ra`).
#                           Otherwise (default), creates a symbolic link (`ln -s`).
