Implementation

• Split the frame: top block = stats header (fixed ~3 lines), middle = scrollable chat log, right panel = sub-agents (see sub-agents task).
• Use ratatui::widgets::Paragraph with Wrap { trim: false } for the header.
• Chat log: build as a Vec<Line> (ratatui spans/lines). Each entry becomes one or more lines. Use Paragraph::new(text).scroll((v_offset, h_offset)) for scroll.
• Horizontal scroll for long lines: track transcript_h_scroll in state, increment/decrement with left/right keys.
• Vertical scroll: transcript_scroll in state, up/down keys.
• Thinking blocks: hidden by default (filter from entries before rendering).
• Tool results: truncated to ~200 chars by default.

Data source

Load RawEntry list from raw JSONL via read_session_file when entering transcript screen. Compute SessionStats for the header.

Blocked by

• app state (claudbg-nq36), event loop (claudbg-ut9q)

Summary of Changes\n\nCreated src/tui/screens/transcript.rs with render_transcript() (4-row stats header + scrollable chat log via Paragraph::scroll) and handle_transcript_event() (Up/k/Down/j/Left/h/Right/l scroll, Tab focus toggle, Esc→back, q→quit dialog). Data loaded lazily via maybe_load_transcript() in run.rs event loop. Thinking blocks skipped, tool results truncated to 200 chars. Subagents populated for future panel. 37 new tests, 184 total passing.
