build(engram): rebuild binary with engram_load_merge runtime (deb0520)

Runtime now includes engram_load_merge — soul daemon awareness.el calls
this function during its periodic sync refresh cycle. Binary rebuilt from
server.el (unchanged source) + updated el_runtime.c.

- * el_platform_win.h — Windows OS-boundary shim for el_runtime.c.
- *
- * Branch: feat/windows-el-runtime. Included ONLY when _WIN32 is defined; the POSIX build is
- * untouched. Goal: let el_runtime.c (a BSD-sockets / dlfcn / fork host) compile and link with
- * mingw-w64 into a native neuron.exe, with no behavioural change to the Linux/macOS build.
- *
- * What it maps:
- *   - sockets  : winsock2 (same call names: socket/bind/listen/accept/recv/send/setsockopt).
- *                Sockets close with closesocket() (see el_closesocket), and the stack must be
- *                started once with WSAStartup — done automatically via a load-time constructor.
- *   - dlsym    : el_runtime.c uses dlsym(RTLD_DEFAULT, name) to resolve callback/tool symbols
- *                exported by the main module. Windows equivalent: GetProcAddress on the process
- *                module. Link the soul with -Wl,--export-all-symbols so the symbols are findable.
- *   - popen    : mapped to _popen/_pclose.
- *   - threads  : UNCHANGED. mingw-w64 ships winpthreads, so <pthread.h> + -lpthread just work.
