If rules hasn't changed, I hope don't rebuild tree.

rules, err := c.loader()

Rule does not change often, and it may be a waste to rebuild the tree every time you execute runCronTab, so I hope loader can tell Controller to stop reload, like

func (c *Controller) reload() error {
    if c.loader == nil {
        return ErrUndefinedLoader
    }

    rules, err := c.loader()
    if err != nil {
        if errors.Is(err, ErrRulesNoChanged) {
            return nil
        }
        return err
    }
// ...
}
