What

Spawning a worker now blanks the inherited resume and session environment variables, so a child process cannot pick up the parent's resume prompt, session id or auth handles.

Details

Cleared: CLAUDE_CODE_RESUME_PROMPT, CLAUDE_CODE_RESUME_FROM_SESSION, CLAUDE_CODE_REMOTE_SESSION_ID, CLAUDE_SESSION_INGRESS_TOKEN_FILE, CLAUDE_CODE_WEBSOCKET_AUTH_FILE_DESCRIPTOR, CLAUDE_CODE_COWORK_FRAME_ARTIFACTS.
CLAUDE_CODE_RESUME_INTERRUPTED_TURN is set to 1 only for relaunches after the first.
