Playwright serializes the function passed to page.evaluate via .toString()
and runs it in the browser context. With main-process minify on, esbuild
renames inlined helpers (e.g. __name) and closure references to two-letter
identifiers like FK/p/ed; their definitions stay at module scope on the
Node side, so the browser eval throws ReferenceError. Mac dev builds were
unaffected because dev mode doesn't minify; only packaged Windows builds
hit this. Main process bundle size is irrelevant (loaded once on startup)
so turning minify off is the cheapest correct fix.
