feat(runtime): workspace_root 제거와 tool 호환을 반영한다

Node store/workspace 위치를 Edge가 내려주는 runtime payload에서 분리한다. Chat Completions tool 요청은 내부 실행에서 tool_choice=none으로 낮춰 downstream 자동 tool 호출 요구로 실패하지 않게 맞춘다.

 Node는 최초 연결 성공 이후 Edge transport가 끊기면 기본 `10s` 간격으로 최대 `10`회 재접속을 시도한다. Edge process 재시작이나 일시 단절이 retry window 안에서 회복되면 사용자가 bootstrap 명령을 다시 실행하지 않아도 Node가 재등록된다. retry 한계를 넘으면 Node는 session/runtime을 정리하고 종료 경로를 탄다.
