…put) - Remove 20px collapsed sidebar view since context usage is now shown in ChatInput - Remove chatAreaRef prop and hysteresis collapse/expand logic - Remove RIGHT_SIDEBAR_COLLAPSED_KEY storage constant - Simplify SidebarContainer to only handle width via customWidth/wide props - Vertical meter still shows on Review tab for continuity
Instead of showing a 20px collapsed sidebar, now fully hides the sidebar when chat area width falls below threshold. Context usage is shown in ChatInput so no information is lost. - Restore chatAreaRef prop and useResizeObserver for width detection - Restore hysteresis collapse logic (800px collapse, 1100px expand) - Return null when hidden instead of showing collapsed meter view - Restore RIGHT_SIDEBAR_COLLAPSED_KEY storage constant

Summary
Adds a horizontal context usage progress bar to the ChatInput component, positioned to the left of the Exec/Plan mode selector. This replaces the need for the 20px collapsed sidebar view that was previously used to show context usage when the right sidebar auto-collapsed on small screens.
