- RAM::copy: swap forward/backward loops so overlapping copies don't overwrite source bytes before reading them (memmove semantics) - copy_dev_to_dev callback: reject when source and destination buffers belong to different devices Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Append §10 (Outcomes) capturing what actually happened during
execution on 2026-05-03:
- the 'keep ours unless theirs is a bug fix' rule and where it
overrode the original §4 plan
- per-PR disposition deltas (especially #298 not adopted, #320
arith wire-up, #310 OpenCL copybuf gated, #327 already absorbed)
- known issues (pocl copybuf crash, MPI gating, intentional SST
absence)
- outstanding deferred work (9b5e664, a537f2a)

Hello. When I tried to run programs that use buffer copy operations, I found that support for these operations was missing. This Pull Request adds the necessary support.
It is designed to work together with the related PR in PoCL for Vortex.
I also added a test, which successfully passed in my CI.
