Function run_events 

pub async fn run_events(
    cfg: &ResolvedClientConfig,
    rollout_id: &str,
    limit: Option<i64>,
    json: bool,
) -> Result<String>

GET /v1/rollouts/{id}/events — chronological event_log stream. CLI subcommand: nixfleet rollout events <id>. Default output is JSON because payload shapes vary by kind — a single rendered table would mislead. json = false falls back to a compact summary (seq / ts / kind / host).
