- Adds persistent browser tools for AI SDK and TanStack AI.
- Adds experimental agents/harnesses/pi to host sessions in Durable Objects.
- Adds eventDelivery: 'terminal' option for runAgentTool.
Bug Fixes
- Fixes agent-tool chunks being duplicated or dropped on reconnect, child re-attach, and fiber recovery.
