Prisma was climbing the directory tree to find a project root and landing at
/app/apps/ which has no package.json. Fix: copy the API schema directly into
apps/orchestrator/prisma/schema.prisma and run generate from within the
orchestrator package context using node_modules/.bin/prisma directly.
This keeps prisma generate fully self-contained within the orchestrator package
and avoids all cross-package project-root detection issues.
