UI Engine Registry Migration

This migration replaces local mirrored UI workspace packages in muonroi-control-plane/packages/* with registry dependencies.

What changed

• Dashboard dependencies moved from workspace:* to versioned packages (^0.1.0).
• pnpm-workspace.yaml now includes only apps/*.
• Root workspace no longer declares packages/*.
• Mirror folder packages/ was removed from muonroi-control-plane.
• scripts/sync-ui-packages.mjs was archived as sync-ui-packages.mjs.deprecated.

Registry/auth setup

All @muonroi/* packages are published to npmjs.org. No scope-level GitHub Packages override is required in muonroi-control-plane/.npmrc.

CI note

Control-plane dashboard CI no longer needs cross-repo NPM_TOKEN/PAT for package install.
