Third stage of the adaptive tool area (shrink -> compact -> collapse). When even the compact panels don't fit, DensitySwap picks a new CollapsePanels widget that keeps a left prefix of panels inline and collapses the rest to buttons; clicking a button opens the full panel as an overlay flyout anchored below it (closes on outside press, mirroring color_select's Floating). A collapsed panel's button shows a live representative tool — the panel's last-used tool (tracked per panel in Ribbon::note_panel_tool on every tool click), defaulting to its first — rendered as a large icon. To support this, render_small now also renders Large* items small and render_large now renders plain Tool/Dropdown items large. Large dropdowns render as icon + label + a bottom arrow strip via a shared render_large_dropdown helper, used in both the full ribbon and collapsed panels. Ribbon dropdowns (tool dropdowns + undo/redo history) now anchor their overlay directly below their widget at any size: a transparent PosReport wrapper records each dropdown button's screen bounds into a thread-local map on draw, and the overlays read it via Ribbon::dd_anchor instead of the layout-estimating compute_*_left helpers.
