foolish-bandit makes Gary admit it isn't finished yet

When a user tries to start a review, draft, or upload a file on this fork and it fails, the app used to shrug and say "could not start the review, try again" - implying a glitch that a second click might fix. foolish-bandit replaced those with a straight answer: the feature will work once the assistant is wired up to its backend. Nothing is wrong; it just isn't connected yet. That honesty saves a user from clicking the same broken button five times.

The same pass fixes a quieter annoyance - a sidebar that forgot whether you'd left it open between sessions - and adds a visible warning strip when a file upload fails instead of swallowing the error silently. The assistant link in the sidebar also gets renamed to "Ask Gary," nudging the product toward a consistent voice.
