Bug Description Every background-agent worker crashes exit 1 before init immediately on spawn — claude --bg, the Agents view, resuming bg chats, and even blank pre-warmed spares all fail. Interactive claude / claude -p work fine. 100% reproducible with claude --bg "anything".

Crash from ~/.claude/jobs/<id>/state.json: exit 1 before init — …at uSK (cli.js:9092:233) at async SKO (cli.js:19558:68) at async h4O (cli.js:19595:313) Bun v1.3.14 (macOS arm64)

Env: Claude Code 2.1.143 (also seen on 2.1.142), macOS arm64. Ruled out: not auth (separate auth_required issue fixed; fresh daemon authenticates, workers still crash), not a version regression (started on 2.1.142), not system Bun (updating it changed nothing). Also: the state.json crash detail is truncated (leading …) so the real error message is never visible.
