…real git-remote-http
…16KiB completes The WASM runner dropped the SOCK_NONBLOCK bit from socket(2) and returned EBADF for fcntl(F_GETFL/F_SETFL) on host-net socket fds, so guest libcurl (git-remote-http, mbedTLS in-guest) ran its TLS socket in blocking mode. Any smart-HTTP upload larger than one TLS record (16384 bytes plaintext) deadlocked: curl checks for an early server response mid-upload, and the blocking recv() waited on a server that was itself waiting for the rest of the POST body. Also allocate host-net fds below FD_SETSIZE (1024) because libcurl's select-based Curl_poll/curl_multi_fdset silently drop fds >= FD_SETSIZE from the pollset, which stalls non-blocking transfers. - wasm-runner.mjs: parse SOCK_NONBLOCK (0x4000) in net_socket, honor O_NONBLOCK via fd_fdstat_get/fd_fdstat_set_flags for host-net sockets, and start host-net fds at 600 instead of 4096. - node_import_cache.rs: bump NODE_IMPORT_CACHE_ASSET_VERSION for the runner asset change.
