Summary

Pipeline engineer task 20260407-041.

Linear: RIG-399

Code review

Found 2 issues:

1. Qwen duration displayed twice in compact view — completed Qwen tasks show elapsed time from the row's dur field, then format_cost_turns calls render_field(Turns) which returns the same duration again via the new QwenCode branch, producing output like ✓ task-id code 3m (qwen/3m).

	// "gemini-2.5-flash" → rest="2.5-flash" → rsplit last → "flash"
	// "gemini-2.5-pro" → rest="2.5-pro" → rsplit last → "pro"
	// "gemini-flash" → rest="flash" → no '-' → "flash"
	let name = rest.rsplit_once('-').map(|(_, last)| last).unwrap_or(rest);
	Some(name.to_string())
	} else {
	Some(task.model.clone())
	}
	}
	AgentRuntime::Codex => {
	// Claude shorthands indicate "use Codex default" — don't show a specific name

2. Gemini model name mangled for preview/versioned models — rsplit_once('-') splits at the last hyphen, so gemini-2.5-flash-preview-04-17 → "17" instead of a meaningful name. The existing test in runner.rs uses gemini-3-flash-preview which would yield "preview". The tests only cover gemini-2.5-flash and gemini-2.5-pro (no hyphens after the version segment).
