docs(sw): AI rules, example E, tests and evidence for the popup / footer / header changes

AI documents (packages/sw/ai)
- SWPopupPropertyRow, SWSelect, SWSlider in the catalog, usage table,
  composition patterns and design rules; SWViewerSlider noted as SWSlider panel.
- Rule: the SWHeader layer / color dropdowns are header-only; popup layer /
  color / line style use SWPopupPropertyRow (property window pickers).
- Footer rules: gra-border-orange surfaces, Model / Layout text unchanged on
  hover, side button hover, vacant surface limited to the slot row.
- Header rules: measured More growing behavior (hysteresis fix A).
- Example E (custom popup) uses SWPopupPropertyRow, SWSelect and SWSlider
  instead of SWHeaderLayerMenu in the popup.

Tests (packages/sw/tests)
- New footer-popup-viewer-refinement.browser.mjs (47 checks: footer stories,
  hover / gradient / tab text / pocket, popup pickers vs property window rows,
  SWSlider, unit SWSelect parity, Popup B, header trace, viewer title art).
- integrated-popup / integrated-consumer: popup pickers and SWSelect instead of
  the header dropdown and the HM UI Select (same overlay / callback / Escape
  requirements).
- integrated-improvement: default sections skip the retired SW/Tool story
  ('tool' still runs by name); storybook-inventory / simplification record the
  retired footer IDs; theme-inheritance widths use sw-footer--full-footer.

Docs (docs/sw)
- sw-footer-popup-viewer-refinement-2026-10-20.md: causes, decisions (the
  first-pass "header dropdown in popup" change is marked withdrawn),
  verification and baseline failures; evidence footer-popup-viewer-refinement-qa
  (47/47). Footer mapping document updated for the removed sections.

Baseline failures (unchanged by this work): home-menu-integration 1,
storybook-unused-removal 5 (10-19 snapshot comparisons), range-cross-browser and
property-panel-comparison open stories retired on 2026-10-19.
