v0.7.4

[0.7.4] - 2026-07-07

Fixed

• Fixed A3S Code TUI transcript wrapping so the welcome banner, user bubbles,
  streaming Markdown, thinking text, pasted images, and tool cards render for
  the scrollbar-adjusted viewport width instead of wrapping a second time.
• Restored reliable transcript wheel scrolling and drag-to-copy behavior by
  keeping mouse capture enabled while copying the app-managed selection on mouse
  release with clamped viewport coordinates.
• Ignored terminal key-release events in a3s-tui so Windows terminals do not
  replay a single key press as duplicate input.
