* fix: V-002 security vulnerability
Automated security fix generated by Orbis Security AI
* fix(ruby): use Ruby allocator macros in jfk_reader and fix memory leak
- Replace calloc/free with ALLOC_N/xfree to match Ruby binding conventions
(ALLOC_N handles overflow checking and raises NoMemoryError on failure)
- Free temporary samples buffer after conversion loop (was leaked)
- Add NULL check for fopen return value with rb_raise
- Add comment clarifying n_samples is a compile-time constant

* fix(ruby): return false instead of rb_raise in memory_view callback
rb_memory_view_get_func_t callbacks should communicate errors via
return value (false), not exceptions. rb_memory_view_get has no
exception-handling wrapper around get_func calls.
