feat: add routes list to demo pages

[olliethedev]

Note

Medium Risk
Touches @btst/stack packaging by changing how plugin CSS is rewritten during postbuild, which can affect published artifacts/consumer styling. Demo changes are mostly additive UI/config updates with low runtime risk.

Overview
Demo apps now have a real home page: demos/*/app/page.tsx is replaced with a route index UI that discovers plugin routes via generateSchema() and (where applicable) expands seeded resources (posts, boards, forms, CMS types/items) into direct links.

Demo configuration/build tweaks: removes root redirects from demo next.config.ts, drops Next’s generated route type import from next-env.d.ts, switches demo tsconfig.json jsx to preserve, bumps demo @btst/stack dependency to 2.5.3, and updates copy-stack-src.mjs to optionally overlay monorepo-built dist/plugins onto the npm install for correct CSS.

Stack packaging fixes: bumps @btst/stack to 2.5.3, changes scripts/postbuild.cjs to inline @workspace/ui CSS directly into each dist/plugins/**.css file (instead of generating shared/ files), and fixes route-docs schema generation to handle Zod defaults where _def.defaultValue may be a value or a function.

Also updates biome.json to ignore the generated .btst-stack-* directories.
