Tours had no switch at all, and the tips switch only covered the app's own rotation — so "I don't want these" was answerable for half of one feature and none of the other. Both are now a row in Settings → Appearance, on by default, and off means off for Hermes as well: an agent tip is dropped at the bridge and a tour request is refused in words, so the agent hears that the walkthrough didn't run instead of narrating a spotlight nobody can see. Renames $tipRotationEnabled to $tipsEnabled to match what it now governs. The storage key keeps the old name on purpose — renaming it would read as unset for anyone who had already turned tips off, and silently turning them back on is the one outcome worth avoiding. The switches stop at the app's edge for now: the tools are still in the model's schema and the calls simply don't land. Withdrawing them entirely needs the setting to reach the backend, which is the next PR.
