AppKit puts the title bar container and window buttons back at their defaults on every live resize step, title change and fullscreen exit. They were corrected from window notifications after that layout had been drawn, so the buttons bounced between positions, or stayed at the defaults when no notification followed. The frames are now corrected in a main run loop observer ordered just before the Core Animation commit, project windows are created hidden on macOS so the buttons are placed before the first frame, and repeated title bar height updates are skipped.
Choosing This Window for a local project in a remote window was routed to the remote host or skipped when the path matched the remote root. open_project and light_edit_open now run on the local backend and leave remote mode once they succeed, project trust for these opens is checked locally, and a failed open cancels the pending close.
IDE zoom changed the toolbar height while the macOS window buttons stayed at a fixed vertical position. The buttons are now centred in the title bar using its measured height and the zoom, and repositioned after AppKit layout updates. Zooming out keeps enough room for them so they do not cover the project icon, and compact mode follows the same alignment.
Windows align from the saved zoom and compact setting when they are built, so the buttons do not move once the page loads. The height uses the zoom the webview applies, so an out-of-range setting cannot misplace them.
