Adds openclaw-plugins/atocore-capture/: a minimal OpenClaw plugin
that mirrors Claude Code's Stop hook. Captures user-triggered
assistant turns and POSTs to AtoCore /interactions with
client=openclaw, reinforce=true, fail-open.
Review verdict: functionally complete, one polish item (prompt
includes wrapper context — not blocking, extraction pipeline
handles noisy prompts). End-to-end verified on Dalidou with a
real client=openclaw interaction.
Both Claude Code and OpenClaw now feed AtoCore's reflection loop.
