… in dev mode This commit introduces the `keepNames` option in esbuild configurations for both application code bundling and Vite utility functions. By setting `keepNames` to `true` (or conditionally based on optimization settings), function and variable names are preserved during the build process. This significantly improves the debugging experience in **development mode** by ensuring that original names are retained in compiled output, leading to more readable stack traces and easier identification of code sections during development.
