Function is_long_lived_start 

pub fn is_long_lived_start(kind: &str) -> bool

Whether a start kind keeps the instance alive.

THE authority. Three hand-maintained copies of this judgement used to exist — the workflow method, config::v2::LONG_LIVED_STARTS, and the capabilities manifest’s own list — and all three disagreed: one had stream and not webhook, one the reverse, one neither. A webhook-only instance under the default run_until: auto therefore reported ready and immediately idle-exited out from under its own listener.
