- The Properties panel's Match button now shrinks to a small icon when the
panel is compacted (render_large gained a `compact` flag), so the panel
actually gets narrower and joins the from-the-right degradation instead
of jumping straight to collapsed.
- A collapsed Properties panel now shows its Match button as the
representative face: item_id recognises PropertiesGroup and
collapse_button renders its match_prop as a large tool.
- The undo/redo history controls are wrapped in PosReport, so their
dropdowns anchor directly below the button (and flip at the edge) like
every other dropdown, instead of falling back to the corner.
- Panel dividers are back: CollapsePanels draws a 1px line between adjacent
panels, skipped only between two collapsed panels.

The tool area no longer swaps every panel between a full and a compact
row together. CollapsePanels is now the whole tool area: it measures each
panel at full, compact and collapsed widths and degrades from the right —
first shrinking a panel's large buttons to compact icon columns one panel
at a time until the row fits, then (only if all-compact still overflows)
collapsing the rightmost panels to their ▾ flyout buttons. Left panels
stay full as long as possible.
Removes the global DensitySwap full/compact/collapse variant selection and
the now-unused build_tool_groups / tool_divider helpers.

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.
