## What changed
- Render spoken user prompts with a bold red chevron, preserving its color during live transcript animation. Trim leading whitespace for display while retaining the raw transcript text.
- Underline and link file references such as `src/lib.rs:42` in spoken assistant transcripts using terminal hyperlinks. Preserve existing links and support Windows-style relative separators.
- Restrict generated file links to existing files with allowed extensions inside the workspace, rejecting hidden paths, traversal, and symlink escapes.
## Testing
Add rendering and transcript tests for the spoken marker, raw text preservation, file links, Unicode column offsets, and Windows-style paths, plus validation tests for rejected file destinations.

## Why
Moving between prompts in backtrack mode rebuilt every transcript renderable and
discarded their cached heights, causing the entire transcript to be laid out
again for each selection change.
## What changed
Rerender only the previously highlighted cell and the newly highlighted cell.
Keep all other renderables, cached heights, and the live tail intact while
continuing to scroll the selected prompt into view.
## Testing
Add regression tests that verify selection changes preserve unrelated height
caches and produce the same viewport and scroll position as a full rebuild,
including with a live tail and terminal width changes.

## What changed
- Render web-link labels in cyan with an underline and hide the repeated destination in recognized terminals with hyperlink support.
- Keep destinations visible for unknown terminals, multiplexers, non-terminal output, and empty labels so the URL remains usable.
- Preserve OSC 8 link targets through prose and table wrapping, streaming updates, transcript clipping, and pager scrolling.
## Testing
- Add coverage for terminal detection, label formatting and fallbacks, wrapped tables and prose, streaming parity, history output, and scrolled transcript rendering.

## Why
Scrolling the transcript pager previously rendered a scratch buffer containing
all rows through the visible viewport, including hidden content above it. This
made rendering work and buffer size grow with the scroll offset.
## What changed
- Add viewport-aware rendering for committed transcript cells and the live tail.
- Forward scrolled rendering through cached and inset renderables while keeping
the full-height fallback for renderables that do not support it.
- Keep hyperlink metadata aligned with scrolled text.
## Testing
Add coverage comparing viewport-aware output with the full-height fallback
across wrapping widths, offsets, insets, styles, hyperlinks, and live tails.
