Desktop search panel overlaps the Windows close button

On Windows, the in-app search panel opens too close to the top-right window controls. When the user tries to close the search panel, the application close button can overlap that area, so it is easy to close the whole Codex app by mistake instead of dismissing search.

Expected behavior

The search panel should be positioned far enough below or away from the window controls that closing search cannot be confused with closing the entire app. Its close target should not overlap the OS/app close button.

Why this matters

Closing search is a small, reversible action, but the current placement can turn it into closing the whole app and losing the current working context.

Steps to reproduce

1. Open Codex Desktop on Windows.
2. Open the in-app search/find panel.
3. Type a query so the search panel is visible near the top of the window.
4. Try to dismiss the search panel from its top-right area.

Actual behavior

The search panel is rendered very high in the window, close to the top-right controls. In the observed screenshot, the red Windows close button overlaps the search panel area, so an attempted search-panel close can close the whole application.
