[r3dbars]

Summary

• add a transcripted-qa sparkle-update-smoke no-publish smoke for fake update-available and downloading states
• expose the menu update callout in the launch UI smoke snapshot
• add scripts/ops/transcripted-qa-bench.sh --mode sparkle-update and update the docs/QA maps so the new lane does not drift

Manual proof boundary

This proves Transcripted-owned UI copy/state for fake local Sparkle updateAvailable and downloading states only. It does not prove live appcast reachability, Sparkle signature/download verification, install/relaunch, an existing installed app upgrade, notarization, Homebrew cask update, or public release publishing. Those stay live/manual release-path proof.

No release was published. docs/appcast.xml and Casks/transcripted.rb were not touched.
