feat: add SSR manifest plugin for AngularNodeAppEngine support (#74)
* feat: add SSR manifest plugin for AngularNodeAppEngine support Add a Vite plugin that generates the Angular SSR manifests required by AngularNodeAppEngine, which previously threw "Angular app engine manifest is not set" because the OXC Vite plugin did not produce them. Changes: - New `angular-ssr-manifest-plugin.ts`: detects SSR builds and injects `ɵsetAngularAppManifest` and `ɵsetAngularAppEngineManifest` into files that reference AngularNodeAppEngine/AngularAppEngine - Add `ssrEntry` option to PluginOptions for specifying main.server.ts - Fix `ngServerMode` define to also be set during dev SSR builds - Add unit tests (vitest) and e2e tests (Playwright) for manifest generation Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: normalize relative path for Windows compatibility in SSR manifest Use Vite's `normalizePath()` on the `relative()` output to convert backslash-separated Windows paths to forward slashes before interpolating into the `import()` expression. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
