Build failed with "failed to write executable" (solved)

TLDR, I fixed by problem and I am unable to reproduce it, this issue is here to let you know something went wrong if it is of some interest to you !

**Problem**

All my Dioxus build failed with the following error (failed to write executable):

After some investigation it seems that the wasm-bindgen executable written in my local directory by the dioxus build was an empty file without execution rights.

I deleted the file, run the build process again, it re-downloaded the tooling and everything was fine.

**Steps To Reproduce**

I was unable to reproduce the problem and now my setup is ok. But it is very likely that the first time I ran the dioxus build on a clean setup I encountered some network problems during the process. So it is very likely that the download process was interrupted and left the `~/.local/share/.dx` directory in a broken state.

**Environment:**

- Dioxus version: 0.7.3
- Rust version: 1.93
- OS info: Linux debian 13
- App platform: Web

Start by examining the Dioxus build process and the ~/.local/share/.dx directory, focusing on how the wasm-bindgen executable is downloaded and validated. Reproduce an interrupted download if possible; done would mean a failed download cannot leave an unusable executable or that the build recovers safely.
