note: Queue routing checked. Embedded `worker` crate execution connection depends on execution backend boundary `00001KW55B32Y`, which has just been accepted and is now inprogress. Leave queued until backend boundary is reviewed/merged/done.

note: Queue continuation requested by user. Dependency `00001KW55B32Y` is closed and validation passed; `00001KW55B33B` has no remaining blockers. `00001KW55B33H` remains queued because it depends on this Ticket.

summary: 前段 `00001KW55B32Y` が closed になったため、embedded Runtime の execution backend 境界に既存 `worker` crate 実行 adapter を接続する。循環依存を避ける adapter placement を選び、理由を Ticket thread に記録し、input を実 Worker run に渡し、`protocol::Event` を Runtime observation bus / Backend WS へ bridge する。config/provider 不足時は typed diagnostic として拒否し、fake/providerless response は再導入しない。

role_plan: Orchestrator が dedicated child worktree を作成し、coder Worker に `crates/worker-runtime`, `crates/worker`, `crates/workspace-server`, 必要な workspace Cargo/package files の write scope を委譲する。reviewer Worker は read-only で adapter placement/dependency boundary、Profile/config/authority resolution、input/run lifecycle、protocol event bridge、Browser-facing non-leak、fake/providerless response absence を確認する。merge/validation/done/cleanup は Orchestrator が行う。`StopPod` は cleanup 時に必ず 1 回ずつ直列実行する。
