Non-blocking version check against RubyGems. Runs in a background thread so it never delays startup. Caches the result for 24 hours to avoid hammering the API.

#notify(timeout: 0) ⇒ Object

Prints a message if outdated. Non-blocking by default: if the check hasn’t finished yet, returns immediately so it can be retried before the next prompt. Notifies at most once.
