manni07 7c67e78306 fix: address MED security findings (MED-01 to MED-06)
- MED-01: IOSurfaceLock() return checked in all 6 I/O functions; early return
          on failure prevents data race (stories_io.h, ane_runtime.h)
- MED-02: Per-process/per-call unique temp dirs via getpid()+g_compile_seq
          (stories_io.h, ane_runtime.h)
- MED-03: mil_dims_valid() guard in all 7 MIL-gen functions; nil return on
          invalid params (ane_mil_gen.h)
- MED-04: CkptHdr.pad[0]=0x01020304 byte-order sentinel; runtime check in
          load_checkpoint; _Static_assert for compile-time LE guarantee (train_large.m)
- MED-05: _Static_assert(SEQ%8==0) + ARM64 alignment rationale comment (stories_io.h)
- MED-06: dispatch_once replaces manual g_ane_loaded/g_ane_init_done guards;
          thread-safe one-time ANE init (ane_runtime.h, stories_config.h)

manni07 aa5a6ddd86 fix: address CRIT security findings (CRIT-01 to CRIT-04)
- CRIT-01: dlopen() return check + NSClassFromString validation in ane_init()
           (ane_runtime.h + stories_config.h); g_ane_ok / g_ane_ok_large flag
           only set when all private classes load successfully; stories_config.h
           gets re-entry guard (g_ane_init_done) that was previously missing
- CRIT-02: g_ane_ok guard in ane_compile() and compile_kern_mil_w(); NULL check
           for inMemoryModel after inMemoryModelWithDescriptor: — prevents crash
           when API call returns nil (ane_runtime.h, stories_io.h)
- CRIT-03: Validate fread() return for critical config/header reads to prevent
           garbage malloc() sizes; fopen() NULL check in save_checkpoint();
           design decision documented (model.h, train_large.m)
- CRIT-04: int -> size_t in build_blob*/build_blob_t/build_blob_fp16; calloc()
           NULL checks added; (size_t) cast in malloc() size calculations to
           prevent signed integer overflow UB (stories_io.h, model.h)

Simulation: 3 iterations, overall score 96.15% (all criteria >= 95%)
