Unexpected References to Server Actions, Turbopack, Hot Reload and DevTools in Production Export Build

### Link to the code that reproduces this issue https://github.com/daniilpanichevornament/next-export ### To Reproduce 1. Configure Next.js with the module: export option. 2. Run the production build. 3. Inspect the output source files for references to server actions, turbopack, hot reload, and devtools **Additional Evidence:** I have identified these issues in the built files: - [Turbopack reference](https://github.com/daniilpanichevornament/next-export/blob/main/.next/static/chunks/main-b45a38056bc69915.js) - [Server actions and devtools reference](https://github.com/daniilpanichevornament/next-export/blob/main/.next/static/chunks/517-0d7e8c6ba2452810.js) ### Current vs. Expected behavior **Expected Behavior:** A production export build should include only the necessary static content without any references to development or server-only features, resulting in an optimized bundle. **Actual Behavior:** The build output contains references to server actions and various development tools, leading to a larger bundle size and unnecessary traffic overhead. **Impact:** This issue might be affecting performance in production, especially under high load, due to the increased bundle size and the overhead of shipping unused code. ### Provide environment information ```bash Operating System: Platform: win32 Arch: x64 Version: Windows 11 Home Single Language Available memory (MB): 16111 Available CPU cores: 16 Binaries: Node: 20.11.1 npm: 10.2.4 Yarn: 1.22.22 pnpm: N/A Relevant Packages: next: 15.1.7 // Latest available version is detected (15.1.7). eslint-config-next: 15.1.7 react: 19.0.0 react-dom: 19.0.0 typescript: 5.7.3 Next.js Config: output: export ``` ### Which area(s) are affected? (Select all that apply) Performance, Turbopack, Server Actions, Output ### Which stage(s) are affected? (Select all that apply) next build (local) ### Additional context I assume that the static export should be completely free of code that isn't used in produc…
