AgentMessage

Show a message that one agent sent to another in a multi-agent run, for example in TaskDetail or in a team activity feed. The header shows the sender and the recipient as colored dot badges (use the same color for an agent everywhere) or everyone when to is omitted, and the time from timestamp (formatTime changes the format). The summary is always visible; content that differs from the summary is revealed with a Show message button, or from the start with defaultExpanded. Labels come from the background task labels (labels).
