[bug] building as a shared lib, app window is running in dev mode

Describe the bug

Hi, I'm working on a poc where I have to build a tauri app as a shared library (expected to be loaded and run from another app). So I build it using classic cargo build --release --lib (note the --release flag).

The thing is, when I load it and run it from another binary, also built with --release, the app window seems to run in “development mode” because it's white blank with the following error message

Could not connect: Connection refused

In my tauri.conf.json I have this (the app use vite + TS setup for frontend)

  "build": {
    "beforeDevCommand": "npm run dev",
    "beforeBuildCommand": "npm run build",
    "devPath": "http://localhost:1420",
    "distDir": "../dist",
    "withGlobalTauri": false
  },

As soon I update devPath property to use the static build assets path "../dist" it fix the issue and it works. But that corroborates my doubts: When running the app from a runner application, tauri app loaded as a shared lib (built in release mode), the window is running in dev mode and it shouldn't. Because devPath is used instead of distDir.

How can I fix this issue?
