Renderer extension hook for commands that want to inject a structured "extra section" between the centralised summary and the centralised hint (review I3 fix to round-1). Implementations write directly to a generic `&mut dyn Write` so tests can capture into a `Vec ` and assert on the rendered stderr output. Production callers receive a write handle wrapping `std::io::stderr()`. Examples: `bsk
| 151 | /// here for `multiple_browsers_online`; the matching ambiguous-label |
| 152 | /// error writes a bullet list of candidate `instance_id`s. |
| 153 | pub trait RenderExtras { |
| 154 | fn write_extras(&self, out: &mut dyn std::io::Write) -> std::io::Result<()>; |
| 155 | } |
