REWRITE RULES
       rewrite is an object where keys are regular expressions and values are
       rewrite rules if the expression matches. Rules may contain references
       to captures of the expression.

       Regular expression and replacement follow ECMA-script rules.

       If no expression matches, the title is left unchanged.

       Invalid expressions (e.g., mismatched parentheses) are skipped.

                "rewrite": {
                     "(.*) - Mozilla Firefox": "<?> $1",
                     "(.*) - zsh": "> [$1]"
                }
           }

       o   window#waybar.solo When only one window is on the workspace
       o   window#waybar.<app-id> Where app-id is the app ID of the only
           window on the workspace
