## Why
Dragging horizontally along the top or bottom transcript row could trigger autoscroll, moving the text under the pointer while selecting it.
## What changed
Require vertical pointer movement from the initial press row before selection autoscroll can begin. Remember that movement so a vertical drag can return to its starting edge and still autoscroll, and preserve the original pointer row across wheel scrolling.
## Testing
Extend regression tests and snapshots for horizontal selection at both edges, stable selected text across repeated ticks, wheel scrolling before the first drag, and autoscroll after a vertical drag returns to its starting edge.

## What changed
- Add incremental, case-insensitive literal search across transcript details, loading older history as needed. Use `F3` to start Find, or `/` in the transcript pager, and navigate matches in either direction. Closing Find restores the previous presentation and reading position.
- Add clickable activity detail controls and `F4` keyboard focus for inspecting individual activity groups in the owned transcript. Preserve expansion state as live activity becomes history.
- Expose configurable `global.find_transcript`, `global.focus_activity`, and `pager.find` bindings under `tui.keymap`. Let new defaults yield to existing custom bindings and show available completions for pending chords.
## Testing
Add regression coverage for Unicode matching, bounded scanning, paginated and changing history, selection during search, composer input isolation, activity controls, and custom shortcut conflicts.

## What changed
- Render transcript history and live output above the composer when `features.transcript_v2` is enabled and alternate-screen rendering is available. Handle scrolling, selection, copying, links, and older-history pagination in the main view.
- Add a clickable return-to-latest control with new-activity hints and temporary clipboard status. Let plain Enter return to latest when the composer is empty.
- Reflow retained transcript content during drawing and preserve the launch-selected screen mode across configuration reloads and session transitions, including `--no-alt-screen` restrictions.
- Enter the alternate screen with its first synchronized frame, and box CLI startup futures to reduce stack usage during session transitions.
## Testing
Add regression coverage for transcript layout, input routing, follow controls, clipboard status, and screen-mode persistence. Add a PTY test for the first alternate-screen frame and clean exit, and extend session-transition coverage through the CLI dispatcher.

## What changed
- Add mouse selection, word and line selection, drag autoscrolling, and keyboard selection with `Ctrl+Space`. Support copying selected text and opening links with a modified click.
- Anchor reading positions and selections to source text so resizing, streaming completion, and history pagination preserve the displayed content. Preserve hard line breaks, indentation, tabs, and graphemes when copying, while excluding display gutters and soft wraps.
- Rejoin activity groups split across history pages while retaining the reader's displayed revision.
- Distinguish confirmed clipboard writes from unconfirmed terminal requests, and retain native clipboard ownership after the transcript overlay closes.
- Manage mouse capture and keyboard modes across overlay transitions, editor handoffs, and suspend/resume.
## Testing
Add regression tests for selection during live updates and pagination, source-text copying across resize, clipboard confirmation and lifetime, and terminal mode restoration.

## Why
Transcript-wide row offsets depend on content that can change during pagination, streaming, and resizing. Computing an exact scroll percentage also requires laying out offscreen history.
## What changed
- Replace the transcript overlay's generic pager with `TranscriptView`, tracking entry identity and a display-row offset through history updates and stream consolidation. Clamp offsets within the entry on resize or replacement.
- Render through bounded layout caches and show `100%` only when following the latest output with no unloaded history.
- Keep the reading position while `Home` loads older pages, then jump to the beginning when loading completes.
- Refresh animations whenever live output is visible, including while scrolled up.
- Reveal selected prompts when backtracking and highlight their text without reversing gutters or padding.
## Testing
Add regression coverage for reading anchors across pagination and live-output completion, resize and consolidation, prompt visibility and highlighting, navigation before the first draw, and avoiding offscreen formatting for the percentage indicator.
