[FEATURE REQUEST] - Color-code subagent invocations in terminal output

When Claude Code invokes a subagent using the Task tool, the output currently appears in standard terminal text. It would improve readability to have color-coded output that visually distinguishes:

• When a subagent is being invoked
• Which type of subagent is running
• The subagent's output/results

This would make it easier to follow complex workflows where multiple agents are involved, especially during mulit-agent coordinated tasks.
