[FEATURE] Add detailed transcript system (ctrl + r) that allows users to view, switch, and navigate between conversations or outputs generated by different subagents

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

When reviewing detailed transcripts that include both main agent and subagent outputs, it's difficult to scroll, locate, and navigate between relevant sections. This makes it hard to track which subagent handled what part of the task.

Proposed Solution

Introduce keyboard shortcuts to quickly switch between, filter, or focus on detailed transcripts or activity logs of specific subagents.

Goals:

• Enable fast navigation between subagents’ detailed transcripts.
• Allow users to filter the activity view by selected subagents.
• Improve overall workflow efficiency when dealing with multiple subagents.

Use Case Example

Example Scenario:

1. You ask Claude Code to analyze Feature 1.
2. Claude Code deploys Focused Agent 1 and Focused Agent 2 to handle specific subtasks.
3. When reviewing the results, the transcript shows main agent + subagents outputs in a long continuous feed.
4. To review Focused Agent 1’s or Focused Agent 2’s outputs in detail, you have to scroll extensively, making the process inefficient and error-prone.
