Now that generated JSON is gitignored, every path that consumes these
files must run generators first. Fixes:
- shell: add bundle-demo-content to dev preamble (eliminates race
between watcher and Next.js on fresh clone); add
bundle-starter-content to Dockerfile RUN chain
- shell-dojo: add predev hook (generate-registry + bundle-demo-content)
- shell-docs: add predev hook (generate-registry + bundle-demo-content
+ generate-search-index)
- ops: replace direct COPY of gitignored registry.json with
generate-registry.ts at build time (copy scripts+shared+packages,
npm ci, run generator)
- Add `engines.node >=18.18` to match Next.js 15 runtime requirements.
- Align `npm run start` with the dev port (3003) for local parity; the
Docker runner sets PORT=10000 via ENV and is unaffected.
- Drop unused dependencies that are not imported anywhere in shell-docs:
`react-markdown`, `react-syntax-highlighter`, `rehype-raw`, and
`@types/react-syntax-highlighter`. These are used in showcase/shell/
but not here; removing them keeps the dependency surface honest.
- Regenerate package-lock.json to match.
