fix(build): include node ui in root build

[Jurij89]

Summary

• Restores repo-root pnpm run build (pnpm build shorthand) as the full developer/release build: no-argument builds run the workspace package build and then the filtered Node UI Vite build:ui task.
• Preserves the previous Turbo passthrough contract for pnpm run build -- ...; forwarded args such as --dry=json and --filter=... go directly to turbo build.
• Adds build:packages as the CI fast path that skips packages/node-ui/dist-ui/ while still running the existing package build graph, including any package-local Vite builds that are part of package output.
• Removes duplicate Node UI Vite build steps from release/publish workflows and refreshes nearby docs so local package and repo-root build commands are clear.

Related

• Regression introduced by PR Tests/improve #227 / commit 58c64b01, which split the Node UI Vite output out of the shared package build but left repo-root pnpm run build (pnpm build shorthand) without packages/node-ui/dist-ui/.

Files changed

File	What
package.json, scripts/build.mjs	Makes no-arg pnpm run build include the Node UI Vite bundle while preserving Turbo arg passthrough for pnpm run build -- ....
.github/workflows/*.yml	Points CI-only builds at build:packages and removes release/publish duplicate UI builds.
README.md, CONTRIBUTING.md, packages/node-ui/README.md	Clarifies repo-root and package-local build commands.

Test plan

• pnpm install --frozen-lockfile
• node --check scripts/build.mjs
• pnpm run build -- --dry=json --filter=@origintrail-official/dkg-core confirmed forwarded Turbo args schedule only @origintrail-official/dkg-core#build.
• pnpm run build:packages -- --dry=json confirmed the CI fast path schedules the package build graph without @origintrail-official/dkg-node-ui#build:ui.
• pnpm turbo run build:ui --filter=@origintrail-official/dkg-node-ui --dry=json confirmed the filtered UI graph schedules @origintrail-official/dkg-node-ui#build:ui after #build.
• Cleared packages/node-ui/dist-ui, then pnpm run build succeeded and recreated packages/node-ui/dist-ui/index.html.
• git diff --check passed with line-ending warnings only on this Windows checkout.

🔴 Bug: this treats any forwarded Turbo arg as a signal to skip the Node UI bundle. That means commands like pnpm build -- --force, --summarize, or even --filter=@origintrail-official/dkg-node-ui now produce an incomplete build with no packages/node-ui/dist-ui, which is easy to miss in local/release automation. Please distinguish "package-only" filters from general Turbo flags, or forward the relevant args to the build:ui step as well.
