Add the ability to review and leave QA feedback on cases that were handled by more than one agent, in Monitors. Reviewers should be able to either leave one comment covering the case and all agents' work as a whole, or leave individual, agent-specific feedback for each agent involved in the conversation.
When a reviewer opens a case in Monitors that involved multiple agents, give them two review options:
- Case-level comment: a single piece of feedback addressing the case and the agents' combined handling of it (e.g., evaluating handoffs, overall resolution quality, consistency across agents).
- Per-agent comment: individual feedback tied to a specific agent involved in the case, scoped to that agent's own contribution.
These options shouldn't be mutually exclusive. A reviewer should be able to leave one overall comment on the case and separate feedback for one or more of the individual agents in the same review pass.
