feat(lab): under a finger, NavigationStack's bar takes the iOS 26 look

+[feat] AppShell accepts `height="adaptive"`: `fill` with a mouse or trackpad, `auto` under a finger (a coarse primary pointer, through the shared touch resolver). With `fill`, the main region scrolls inside a viewport-high shell, so a phone browser never sees the page scroll: its toolbar or address bar does not minimize, and on iOS a status-bar tap does not return to the top. `adaptive` lets the page scroll under the sticky header under a finger and keeps independent scroll regions with a mouse. The root now reports which element scrolls in `data-scroll-owner` (`content` for the main region, `document` for the page), for code that listens to or restores the scroll position. `fill` and `auto` are unchanged, and `fill` stays the default.

+[feat] AppShell: under a finger (one touch model on every touch device), when the page scrolls (`height="auto"`, or `height="adaptive"` on a touch device), the pinned header looks like an iOS 26 bar. It paints no background of its own and draws no divider. Once the content has moved more than 10px under it, a veil of the header's colour fades in at its top on iOS's measured spring (0.29 s): strongest at the top, gone just below the header. It fades out (0.51 s) when the content comes back. A scroll the program drives (`scrollTo`, a status-bar tap) switches the veil at once instead: on iOS 26.2 a fade that starts on such a scroll makes WebKit drop the header's items for a frame or two. Under Reduce Motion the fades are the animator's 200 ms cross-fade. Where the browser supports `prefers-reduced-transparency` (Safari 26.2 does not yet), Reduce Transparency makes the veil an opaque band ending at the header's bottom edge. With a mouse nothing changes. The springs and the veil's shape are internal measured constants; the veil takes the header's theme colour.

+[fix] `astryxStylex` resolves `defineConsts` values read from another file. With the `{stylexOptions}` form (the one Storybook uses), a file that read only constants from a `.stylex.ts` module lost that import once StyleX compiled it, so the constants never reached the CSS: a constant used as a media-query key failed the build ("Invalid empty selector") and one used as a value shipped as a custom property nothing declares. In either form, a constant defined on the other side of the layer split, or in an Astryx package (compiled with the library class-name prefix) and read from an app file (compiled with its own), stayed unresolved.

+[chore] Internal: the gesture host becomes the one document-level touch owner: the finger count, touch gates, and a kept press for continuous-tracking controls, whose element gets `touch-action: manipulation` where the pointer is coarse. A scroll lock's page hold and the finger-scroll watch keep their own listeners and ask the host only about the touches it owns. A second finger fails a one-finger pan that has not claimed, so the page can pinch. A scroll-edge pan holds a lone finger from the first move that pulls away from an edge every scroller under it is at, so those moves are cancelled before it begins; with a second finger anywhere on the screen the page keeps its pinch. Where the primary pointer is fine, the host attaches nothing and registers no listener, following the pointer when it changes; a recognizer that reads each event's pointer itself opts out with `perEventPointer`, and a press tracker with it paints a finger's press feedback only, with no control event and no mouse or pen press. A press tracker whose hold acts (a stepper's hold-repeat) can bring a selection lock for its presses, as a recognizer can. Internal, for the touch components that adopt them; not exported from the package entry point.

Under a finger, while a row is pressed and through its release, the press paints on the row's `::before` and the row is its own stacking context; at rest nothing of it applies, so a row's own `::before` decoration and its children's stacking are as they were. During a press the layer is the row's `::before`, so a caller's decoration there takes the layer's box and paint for that time (a page stylesheet keeps the properties it sets); decoration that should stay through a press belongs on `::after` or a child element. With a mouse or trackpad the row is unchanged: no layer and no new stacking context.
