The new proxy-wasm-cpp-sdk uses ALLOW_MEMORY_GROWTH=1, allowing WASM
memory to grow dynamically. This caused Buffer::copyTo to fail when
requesting more data than the buffer contains, as allocMemory now
succeeds for large allocations instead of failing. Added explicit bounds
validation before allocating to ensure the requested range is within
the buffer's actual length.
