fix(coding-agent): expect allowAskReopen in merged tree-summary navigateTree assertions

Upstream's shift+enter summarize-and-switch test file (f33465a97, brought in
by the upstream/main merge) asserts navigateTree's options literally, but
this PR's ask-reanswer flow always passes allowAskReopen: true. Update the
NavigateTree mock type and the four call assertions to match.
