Remove the 4 floating action buttons from the titlebar and replace with a single compact dropdown trigger (▾) that opens a combined menu showing all categories (File, Edit, Search, View) with section headers. Reduce titlebar height from 40px to 30px so tabs and title move up. https://claude.ai/code/session_013uWpT9xBhNcN2PtRU4XotZ
Set TABBAR_H to 0 and increase TITLEBAR_H to 36. Tabs are now rendered inline in the titlebar after the dropdown button, with tab click handling moved into the titlebar region. The separate render_tabbar() is now a no-op. This puts the dropdown icon, tabs, and window controls all on one line, eliminating the second row. https://claude.ai/code/session_013uWpT9xBhNcN2PtRU4XotZ
Reorder titlebar: tabs start from left edge, then (+) new tab button, then (▾) dropdown trigger. The + and × (close tab) icons now use font_ui instead of font_ui_small for better visibility. Dropdown button position is computed dynamically and stored in dropdown_btn_x so wndproc hit-testing stays in sync. The dropdown menu panel now appears below the trigger button wherever it ends up. https://claude.ai/code/session_013uWpT9xBhNcN2PtRU4XotZ

This PR refactors the UI layout to integrate tabs and the dropdown menu directly into the titlebar, eliminating the separate tabbar and improving space efficiency.
Summary
The editor previously had a separate tabbar below the titlebar for tab management. This change moves tab rendering and interaction into the titlebar itself, and consolidates the menu system into a single dropdown button positioned after the tabs. This creates a more compact, modern interface similar to contemporary text editors.
