Function render_status_with_failures 

pub fn render_status_with_failures(
    plugins: &[PluginStatus],
    failed: &[FailedLoad],
) -> String

WT.4: render_status plus a trailing section for plugins that tried to load and could not.

Trailing, and deliberately so. The interactivity layer maps cursor.line - HEADER_LINES into the loaded-plugin list, so anything inserted above or between the rows would put chords on the wrong plugin. Failed entries have no host id to unload or reload anyway — they are a report, not a row you can act on — so appending them costs the mapping nothing.

Why it exists at all: a plugin that failed to load is otherwise indistinguishable from one that was never installed. That is precisely what made the reported failure take a debugging session — org was absent, and absent looks the same either way.
