* fix(frontend): default to Webpack over Turbopack in dev to avoid PostCSS worker leak on macOS On macOS arm64, Turbopack + Next.js 16.2.11 + Tailwind CSS v4 causes an unbounded spawn of PostCSS evaluator processes that consume high CPU and memory and never return a response. Webpack is unaffected. Change the no-override default in getDevBundler() from platform-dependent Turbopack (all non-Windows) to Webpack. DEER_FLOW_DEV_BUNDLER=turbo continues to work as an explicit opt-in for local diagnosis. Fixes #5132 * docs(frontend): address webpack default review feedback * docs(frontend): clarify webpack default rationale
