chore(release): bump versions to source manifestRootsToUpdate

Previously the four ng-packagr libs (chat, langgraph, ag-ui, render)
had release.version.manifestRootsToUpdate pointing at dist/{projectRoot}.
That meant 'nx release version' wrote new versions to dist/ (gitignored)
but never to the source libs/<lib>/package.json — so source files stayed
at 0.0.1 forever and only the build-output got bumped.

Switch to ['{projectRoot}'] so source is the authoritative version.
The build's preVersionCommand re-runs to populate dist with the new
version before publish.

The TS-only libs (a2ui, partial-json, licensing) already used the
default (source manifest) so this is purely a fix for the four
ng-packagr libs.
