Closes #374 (adapted, not 1:1 merged). @hnshah opened PR #374 proposing a docs/adr/ directory for architecture decision records. The intent is right -- the "why is search-quality eval manual?" reasoning drifts out of memory if it isn't written down -- but the docs/adr/ convention doesn't fit alongside the existing docs/solutions/ structure (compound-engineering ce-compound pattern with frontmatter metadata, additive entries, no membership-contract test). This commit adopts hnshah's ADR 002 content (search-quality eval is manual by default) as a docs/solutions/architecture/ entry with the canonical compound-style frontmatter (module, problem_type, applies_when, related_components, tags). Drops the docs/adr/ directory pattern, the README index, and the test_adr_docs.py contract test. ADR 001 (multi-surface packaging) is intentionally not adopted here: it referenced sync.sh as the deploy mechanism, but sync.sh was removed in PR #405 in favor of `npx skills add . -g -y`. The multi-surface packaging story is still real but has moved beyond what the original ADR captured; a fresh "how we ship to multiple harnesses" entry would make sense as a separate doc.
