Add public API for aligned memory allocation, exposing the existing mem_allocator_malloc_aligned infrastructure through wasm_export.h. - Add wasm_runtime_aligned_alloc() API declaration with documentation - Implement internal helper wasm_runtime_aligned_alloc_internal() - Add public function with size/alignment validation - POOL mode only, returns NULL for other memory modes - Follows wasm_runtime_malloc() patterns for consistency Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
