serve: early-return for socket, skip network options resolve

Users installing with pnpm or --ignore-scripts now see a clear explanation
of why the native binary is missing and exact steps to fix it. The shell
script wrapper provides more actionable guidance than the previous Node.js
fallback that only suggested running the postinstall script without context
about why it wasn't run automatically.

+## User-Facing Rendering
+
+HTTP serialization and user rendering are separate boundaries. The server
+should send structured public errors; CLI and TUI code should format those
+structures through one shared formatter.
+
+For SDK calls using `{ throwOnError: true }`, the generated client may wrap the
+decoded response body in an `Error`. The original body should remain available
+under `error.cause.body`; `FormatError` is the right place to unwrap and render
+that body. TUI aggregation helpers should call `FormatError` first, then fall
+back to generic `Error.message` / string rendering.

+When several parallel startup requests fail from the same underlying issue,
