Paul BakausandClaude Fable 5.1 66482a9808 Port: Fix flat type hierarchy false positives (#702)
Upstream sha 84728e9ce4.

The rule now reads rendered semantic roles and the dominant size per role
instead of the raw set of font sizes on the page, and it fires only when
every adjacent role step is under 1.25x.

- crates/core checks::rules gains TYPE_HIERARCHY_SELECTOR / MIN_ROLES /
  MIN_STEP_RATIO, typeHierarchyRole, dominantTypeRoleSize and
  checkFlatTypeHierarchySamples, the shared half of checks.mjs.
- crates/core browser::page_checks gets checkFlatTypeHierarchyFromDoc over
  the Dom trait, with the overlay skip selector checkTypography passes.
- crates/html page.rs gets the same walk over StaticDocument.
- crates/detect drops the source-only analyzer: flat-type-hierarchy leaves
  REGEX_ANALYZERS, the text-content analyzers shift to index 1, and
  analyzer_rule_id loses its first row.
- crates/html cascade defaults gain contentVisibility, and crates/foundation
  registry carries the reworded description.

Goldens re-recorded (the binary now matches origin/main's JS engine on every
one of these fixtures, verified by scanning the shared corpus with both):
glow, icon-tile-stack, layout, modern-color-borders, motion,
named-color-borders, numbered-section-markers, oklch-neon-text,
typography-should-flag, json and text.
