shipit-watcher 1.2.1

stale now means stale.

A prompt nobody has registered is re-served from cache on every request once its TTL expires. That was reported as serving stale prompt, which reads as a Langfuse outage and sends people hunting for a problem that is not happening — it is the ordinary steady state for an unregistered prompt, and the fallback ladder working as designed.

ManagedPrompt.stale now tracks whether the cached value actually came from the registry, and the warning only fires when a real registry value could not be refreshed.
