pub async fn handle_sync(auto: bool, quiet: bool) -> Result<()>Expand description
shine theme sync [--auto] [--quiet]. Prints eval-able shell export
statements to stdout; diagnostics go to stderr (suppressed by
--quiet). Always exits successfully — an unresolved theme prints
nothing rather than failing, so an old/broken binary or an unsupported
terminal never blocks shell startup (PRD §7).
