Make the pre-handoff prompt review a confirm instead of a 3-way menu (#37)

A select with proceed / review / cancel asks the user to weigh three
options at the one gate that should be easy to clear. Collapse it to a
confirm where the primary is proceed and the secondary opens the prompt;
Ctrl+C already means cancel everywhere else in the flow.

Carry proceedHint onto the confirm shown after a review too. That confirm
is what actually authorizes the run, so the "runs autonomously in …,
auto-accepting edits" wording must not disappear just because the user
chose to read the prompt first.

+Replace the three-option pre-handoff prompt review with a Yes / "review first" confirm (Ctrl+C cancels), and carry the autonomy hint onto the post-review confirm so choosing to read the prompt first doesn't drop the wording about what the run auto-approves.
