feat(sw): integrated improvement 0.2.0 (popup content, header open, tool buttons)

SW package 0.2.0 integrated improvement (Task A, steps 1-8). All new props are
optional; existing SW Stories are pixel-identical to the previous build (28/28).

- Build reproducibility: dist text normalized to LF, dist/build-info.json
  (commit, dirty, tool versions, no timestamp), packages/sw/.gitattributes
  (eol=lf). LF checkouts give identical dist and tarball.
- SWHeader: documentOpenPlacement ("menu" default | "header": Open right of
  the logo in the existing document-button look, reusing onDocumentOpen and
  documentOpenLabel, no duplicate Open in the dropdown), leading slot,
  hiddenControls sub-items documentNew / documentOpen / layerFreeze /
  layerLock. Open moves into More on measured overflow (with hysteresis).
- showNew / showOpen (SWHeaderDocumentTitle), showFreeze / showLock (layer
  menu, field, property window list).
- SWToolButton (text / pill / document) and SWToolGroup (radio selection),
  reusing the existing toggle, pill and file-name looks.
- SWPopup / SWPopupSection / SWPopupRow on the shared property window frame;
  SWHeaderPropertyPanel gains children, title, autoFocus and optional
  selection / properties / groups. Escape stack for several popups.
- Field dropdowns inside a popup use the shared fixed overlay
  (useSWFixedDropdownPosition), so the scrolling body no longer clips them.
- AI guide, examples E/F, README, Storybook (SW/Header/Options, SW/Tool,
  SW/Popup) and verification record docs/sw/sw-integrated-improvement-2026-10-19.md.
- Regression scripts rescoped for the intended changes (unused-removal 81/81,
  overview 52/54 with the two pre-existing historical assertions).

Known limitation (unresolved): tools / leading content (incl. SWToolGroup)
does not move into More. With a wide tool bar the configured fields shrink
instead; in Example F the document name and layer field reach 0px at 390px.
