Idea:

• Allow clock-rs to listen for a POSIX signal (e.g., SIGUSR1).

• When the signal is received, the running clock-rs instance reloads its config file without needing a full restart.

• This would let users do the same thing as Cava’s post_hook—apply a new theme or config dynamically.

Why it’s useful:

• Users can switch themes, update colors, or change formats on the fly.

• Makes integration with scripts, templates, or dotfile managers seamless.
