fix: replace tsc --build with tsc to prevent parallel build race condition

When Nx runs builds in parallel and restores core/react from remote cache,
multiple tsc --build processes simultaneously try to rebuild the same project
references, causing race conditions where one process reads partially-written
declaration files. Since Nx already handles dependency ordering via ^build,
the project reference traversal in tsc --build is redundant.
