This header defines jh::pod::bytes_view — a low-level, read-only, non-owning abstraction over raw memory regions. It enables safe reinterpretation and controlled cloning of memory blocks into POD-compatible types.

Design Goals:

• Fully POD (const std::byte* + uint64_t)
• No ownership, no destructor, no STL containers
• Support for reinterpretation (at, fetch)
• Stack-safe and heap-safe cloning (clone)
• Works seamlessly with pod_like and trivial_bytes types

Note

This type assumes the data lifetime is externally guaranteed. It is ideal for parsing binary payloads, memory-mapped blobs, protocol headers, or arena-based serialization systems.
