Support TypeScript-solution workspaces in the application generator #219

Problem

The application generator only supports classic Nx workspaces, where projects use project.json and libraries resolve through tsconfig.base.json path aliases. In a TypeScript-solution workspace (project references, workspace packages, nodenext resolution), generated Forge apps don't build.

New Nx workspaces are increasingly TypeScript-solution workspaces. For example, when create-nx-workspace 24 runs inside an AI agent, it ignores --preset=apps and creates one from the nrwl/empty-template template. This also means the e2e suite tests a different workspace layout depending on whether an agent runs it.

Proposed solution

Support both layouts, following the upstream @nx/node application generator (packages/node/src/generators/application):

1. Detection: use isUsingTsSolutionSetup(tree) from @nx/js/internal in normalizeOptions.
2. Project definition: in TypeScript-solution workspaces, write the app's package.json (with an nx section) instead of project.json, add a useProjectJson option like upstream, and register the app in the workspace with addProjectToTsSolutionWorkspace.
3. TypeScript config: set module and moduleResolution to nodenext in tsconfig.app.json and add project references with updateTsconfigFiles.
4. Output path: use upstream's <projectRoot>/dist convention in getForgeOutputPath, so the build output and the Forge targets still agree.
5. Graph plugin: createNodes only creates a Forge project if there's a project.json next to manifest.yml. It also needs to accept a project defined by package.json.
6. Package executor: check that package.json generation for the Forge bundle works when the app has its own package.json and depends on workspace libraries through workspace:*.
7. E2E: run application.generator.spec.ts against both layouts, with the workspace layout chosen explicitly rather than depending on the environment.

Notes

• Comes after the Nx 24 update (Support Nx 24 #217, feat(nx): support Nx 24 #218).
• This is a new feature, so it ships as a minor release. Classic workspaces keep working as before.
