Fix: Add defensive checks to prevent tmux configuration for invalid users

- Modified 'roles/tmux/tasks/main.yml' to explicitly filter out
  the root directory ('/') as a valid home directory.
- Modified 'roles/tmux/tasks/tmux_config.yml' by adding a conditional
  check () to all tasks. This prevents the
  tasks from running for users with invalid home directories, which
  resolves the 'chown failed' error.
