fix(coding-agent): preserve editor content during tree navigation summarization (#1169)

Do not overwrite editor text with the rewound user message after
navigateTree completes if the user has already typed something during
the summarization wait. Applies to both the /tree selector and the
extension-driven navigateTree handler.
