Claude Bot 6411ae5ef0 fix(server): show proper DNS error instead of EADDRINUSE for unresolvable hostnames
When `Bun.serve()` is called with a hostname that cannot be resolved
via DNS (e.g., `something.localhost`), the error message now correctly
shows `getaddrinfo EAI_NONAME` with code `ENOTFOUND` instead of the
misleading `EADDRINUSE` error suggesting the port is in use.

The fix captures the `getaddrinfo()` return code in `bsd.c` and maps it
to libuv-style error codes (UV__EAI_*), which are then detected and
displayed properly in `server.zig`.

Fixes #25765
