feat: v0.3.0 — Phase 3/4 façades + AppLayout on AppShell

- Curated re-exports from @limitless/ui through /forms, /data,
  /feedback, /navigation, /utils sub-paths so apps stop importing
  from the lower layer.
- /forms also re-exports the full @limitless/ui validation surface
  (hooks, format/security/address validators, types).
- AppLayout is now a thin wrapper over @limitless/ui's <AppShell> —
  same ShellConfig DTO, no duplicated chrome code.
- shell/types + shell/index re-export from @limitless/ui to keep one
  canonical type and one shared context.
- auth middleware: loose NextRequestLike typing to avoid two-copies-
  of-next conflict with the consumer's next.
- postbuild: rewrite ../images/ to ./images/ in copied CSS so refs
  resolve in dist/styles/.

Widget family in /data is the intersection of limitless's two
Widget files (Widget.d.ts vs Widget/index.d.ts collision in dist);
upstream fix needed before exposing IconWidget/UserWidget/etc.
