📝 Walkthrough

Walkthrough

CodeRabbitのハイブリッド運用構成（ADR-019）とタクトfix/superviseファセットの統合戦略（ADR-020）を定める2つの新規アーキテクチャ決定記録を追加しました。併せてCLAUDE.mdに参照を追加し、docs/todo.mdを更新して後処理AI統合の計画を明確化しました。

Changes

Cohort / File(s)	Summary
Architecture Decision Records docs/adr/adr-019-coderabbit-review-hybrid-policy.md, docs/adr/adr-020-takt-facets-sharing.md	2つの新規ADRを追加。ADR-019はCodeRabbitレビューのハイブリッド運用フロー（プロジェクト適用性フィルタ、重要度分類、再プッシュポリシー）を定義。ADR-020はpre-push-reviewとpost-pr-reviewワークフロー間でのファセット共有戦略と設計原則を記述。
Documentation Updates CLAUDE.md, docs/todo.md	CLAUDE.mdにADR-019とADR-020への参照を追加。docs/todo.mdを更新し、cli-merge-pipelineへのAIステップ統合計画を具体化（environment変数渡し、背景実行制約、検証要件）。

work item that instructs adding [[merge_pipeline.post_steps]] with
".claude/hooks-config.toml" so implementers use the actual file; ensure the
surrounding tasks (mentions of src/cli-merge-pipeline/src/main.rs run_steps "ai"
