Subject: [PATCH] fix(desktop): strip Windows verbatim prefix from runtime
 spawn paths (#8936)

Tauri's resource_dir() returns \\?\ verbatim paths on Windows, so the
bundled Node executable and the cli-entry.js argument were spawned with
that prefix. Node's entry-script resolution cannot handle it and dies
with EISDIR before the daemon reports its listening URL, making the app
unstartable regardless of workspace. Simplify both paths with dunce
before spawning, complementing the workspace-path fix from #8615.

Fixes #8929
