Claude Code ships v2.1.208-2.1.213 with agent-safety controls

Session-wide WebSearch caps, per-session subagent spawn limits, auto-backgrounding of long MCP calls, /fork into background sessions, and a screen-reader mode. 2.1.212 fixed a plan-mode bug that ran file-modifying Bash without permission. Upgrade to 2.1.213 and use the new caps to bound runaway agent runs.
