Write crates/mohu-buffer/README.md

[Bbn08]

Summary

crates/mohu-buffer is the memory foundation of mohu and the most complex crate in the workspace, but it has no README.md. New contributors reading the codebase cannot understand the Buffer/Layout/RawBuffer architecture without reading thousands of lines of source.

What to do

Create crates/mohu-buffer/README.md covering:

1. One-paragraph description of the crate's role (typed, reference-counted, strided byte storage).
2. Architecture diagram in ASCII: Buffer = Arc<RawBuffer> + DType + Layout + BufferFlags.
3. A table of the 5 public modules and what each owns (alloc, buffer, layout, ops, pool, strides, view).
4. Code example showing: Buffer::zeros, Buffer::from_slice, reshape, transpose, as_slice.
5. A section on DLPack: to_dlpack / from_dlpack with the safety contract.
6. A section on copy-on-write semantics: share() vs make_unique().
7. Link to workspace CONTRIBUTING.md.

Acceptance criteria

• crates/mohu-buffer/README.md exists.
• Code examples compile (cargo test --doc -p mohu-buffer).
• ASCII architecture diagram is present.
• DLPack and CoW sections present.
