Wrap built-in TUI status lines within the footer row budget (#60682)

## Why

Long built-in status lines were truncated to a single row even when the footer had room for more content.

## What changed

- Wrap status text to the available width and row budget, preserving styles and hyperlink targets across rows.
- Show an unlinked ellipsis when content exceeds the available space.
- Refresh wrapped content when the status text, agent label, or width changes.
- Keep reasoning-effort transitions on one row and restore wrapping after the final animation frame.

## Testing

Add coverage for wrapping and hyperlink boundaries across footer layouts, content and agent-label updates, resizing, and wrapping restoration after an effort transition. Update transcript and startup snapshots for multiline status text.
