Move the Claude command/agent files from claude/ to adapters/claude/ to
match the adapters/<vendor>/ layout, and add the subagent definitions
(evaluator, exerciser, researcher, reviewer, security-auditor,
start9-spec-checker) plus the full-eval command wrapper.
Move the handoff checklist body into guides/handoff.md as plain prose,
and replace the Claude command with a thin wrapper that reads the guide,
matching the full-eval pattern.
