Wrap Claude and Codex setup adapters

[cafitac]

Summary

• add thin Claude Code and Codex setup/health adapter wrappers on the existing orchestrator-neutral DTO layer
• keep task submission/event/reply/cancel lifecycle methods explicitly unsupported so existing MCP/channel runtime paths remain unchanged
• document PR-04 status and update the adapter architecture roadmap/changelog

Status mapping

• Claude print-only -> AdapterInstallStatus.PRINTED; fix -> REGISTERED / UNCHANGED / FAILED; health -> PASS / WARN / FAIL from existing MCP registration inspection
• Codex print-only -> AdapterInstallStatus.SKIPPED; fix delegates to codex-channels, marketplace, MCP registration, and legacy hook cleanup helpers, then maps to REGISTERED / UNCHANGED / FAILED; health -> runtime version PASS or missing-runtime WARN

Runtime scope

Wrapper-only. This does not rewire CLI dispatch, MCP server runtime, Claude channel notifications, codex-channels runtime delivery, or task lifecycle handling.
