🤖 AI code review

This PR reworks the multi-harness architecture wiki page to describe the agent workspace as the durable identity and the various LLM CLIs as interchangeable runtimes. It introduces new layer and support-level tables, elaborates on resilience and A/B testing rationale, and details the staged Pi adapter integration. The front-matter description and quality value are also updated.

Safe to merge — no P0/P1 findings
