fix(dev): tsx watch not detecting workspace package changes

tsx watch's symlink-based file watching doesn't trigger on changes to
pnpm workspace packages (tsx#221). Add --include flags for packages/core
and packages/node-runtime source directories to both dev:serve script
and vite.web.config.mts auto-serve plugin. Extract long command to
scripts/dev-serve.sh for cleaner package.json.
