module runner full reload error when importing node_modules dependency as entry

[hi-ogawa]

Describe the bug

I use my own package as module runner entry server.environments.ssr.runner.import("my-package"), but this causes an error on full reload hi-ogawa/vite-plugins#742.

Here is a minimal repro:

$ node repro.js
[vite] connected.
[TEST] file:///home/projects/github-5yembwxu/node_modules/.pnpm/file+fixtures+test-dep/node_modules/test-dep/index.js
[vite] program reload
[vite] An error happened during full reload
Failed to load url test-dep.js (resolved id: test-dep.js). Does the file exist?
Error: Failed to load url test-dep.js (resolved id: test-dep.js). Does the file exist?
    at loadAndTransform (file:///home/projects/parigpvogv.github/node_modules/.pnpm/vite@6.3.4/node_modules/vite/dist/node/chunks/dep-Bn81Esdm.js:35788:17)

Now that #19283 is fixed, this can be worked around by wrapping entry with a virtual module, but I suspect there's still minor resolution issue around module runner and fetchModule.
