- Fix main grid columns: split activity bar and explorer into separate columns to restore explorer visibility and eliminate right-side blank space.
- Remove duplicate chat header to fix double top bar in chat dock.
- Make chat logs tab dev-only (import.meta.env.DEV).
- Gate backend debug logs behind debug_assertions (lib.rs, ai.rs, settings.rs).
- Add devConsoleError helper to suppress console.error in production.
- Ensure stable useCallback dependencies.
