Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthrough開室中の通話ルームで、現在のホストがアクティブな参加者へホスト権限を移譲できるようになりました。バックエンドAPIと公開型、フロントエンドの操作、役割変更後のセッション処理、および関連テストを追加しました。 Changes通話ルームのホスト移譲

Suggested reviewers: Merge Risk: 🟡 Moderate · up to Host transfer works in the normal case, but two cases should be handled before merging. A participant who has lost Calls permission can still be made host. If the notification after a transfer fails, the transfer is still applied, but the host sees an error and other participants are not updated. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Host transfer has strong authentication and transactional protections, but it can grant ownership to a participant whose Calls permission has been revoked. A concurrent departure can also leave the transferred room without an active host. Exposure is limited to a room whose current owner initiates the handoff; existing media authorization remains effective. Retained concerns

Review comments at @packages/backend/src/core/calls/CallsRoomService.ts:
- Line 685: Update the ownership-transfer flow in CallsRoomService so a failed
callsEventService.publish after the transfer is committed does not make the
operation unrecoverable: retain or otherwise expose the pending
participant-update notification so it can be retried independently of the
old-host ownership check, allowing participants to synchronize with the
committed state.
- Around line 665-666: In transferHost, validate the target participant’s
current Calls access with assertCanJoin using participant.userId before changing
their role to host; do not rely only on the active state and role checks.

What
Calls の参加者メニューに「ホストを譲る」を追加します。現在のホストが確認すると、相手がホストになり、元のホストはスピーカーとして残ります。元のホストが退出しても通話は継続します。
calls/rooms/transfer-hostを追加し、所有者と両者のロールを同一トランザクションで更新します。移譲先の現在の Calls 参加権限も確認します。リスナーが新しいホストになった場合は音声へ再接続します。Why
VC モデレーターの追加はできても、通話を続けたままホストを交代できなかったためです。関連: #17
Additional info (optional)
対象は通話中のルームと参加中のユーザーです。相手が別の稼働中・開始前の個人ルームを所有している場合は拒否します。フォロワー限定の閲覧判定は新しい所有者に切り替わり、元のホストと現在の参加者には閲覧権限を保持します。

既存のデータ構造を使用し、スキーマ変更はありません。ルーム内の host は1人、稼働中の個人ルームは所有者につき1つという制約を維持します。
