vite: /ns/m dev server 404s on pnpm-isolated transitive dependencies #11470

Build-time / dev-server error in @nativescript/vite (observed on 8.0.11, same code on main).

Description

Under pnpm's nodeLinker: isolated, a package's transitive dependency lives in that package's own node_modules (or .pnpm/.../node_modules/), not under the app root or the workspace root. The /ns/m module server only probes projectRoot and workspaceRoot (resolveCandidateFilePath in hmr/server/websocket-module-specifiers.ts), so requests for such files 404 and the dev-session boot fails:

Dynamic import error: Error: Instantiation failed (http-loader):
http://<host>:5173/ns/m/src/index.ts — HTTP import failed:
.../ns/m/node_modules/@nativescript-community/ui-image/... (network error)

Repro: a monorepo where an app imports a workspace package whose own dependency is a NativeScript plugin (e.g. @octane-xplat/gif → @nativescript-community/ui-image) — the app's node_modules contains no ui-image, so /ns/m/node_modules/@nativescript-community/ui-image/index-common.js can't resolve from either probed root.

Suggested fix

Probe each workspace package's node_modules directory (or use proper module resolution from the referring file's location) as a fallback before 404. In our tree, adding that fallback plus platform-suffixed candidates (.ios.js, .android.js) to the node_modules probe unblocked the whole module graph.

Environment: pnpm nodeLinker: isolated, @nativescript/vite 8.0.11, Vite 8.3, iOS simulator.
