Fixes + packaging + docs since 0.3.0:
- Move 10 story-only @patternfly extension packages + victory from
  dependencies to devDependencies (no consumer bloat).
- Add a package README (with hero images) so npm shows one; fix both READMEs.
- Glass fixes: hero rounded-corner artifacts (backdrop-filter / border /
  overflow), Compass full-demo full-bleed header, modal mobile sidenav,
  rails-hidden main margins, mobile avatar alignment.
- Relocate shared story kits to src/components (DemoKit/StoryKit/AcmeLogo/
  AcmeMasthead); story + foundations QA passes.
- CI: Node 22, Playwright install fix, npm-upgrade for OIDC publish.
