feat: add agent_type field and support Agent tool rename from CLI v2.1.69

- Parse agent_type from SubagentStart hook events and forward via claude:agent-update
- Support renamed Agent/Agent(type) tool alongside existing Task/Task(type) syntax
- Fall back to prompt field when description is absent in Agent tool input
- Display agentType (with subagentType fallback) in agent monitor badge
- Show agentId as tooltip on the type badge when available
