[BUG] Esc with several queued messages delivers them one per keypress instead of all at once

Environment

Claude Code 2.1.266, darwin-arm64, terminal CLI.

Steps

1. While a turn is running, type three or four messages, each submitted with Enter, so they queue.
2. Press Esc once.

Observed

• Esc interrupts the turn and delivers exactly one queued message, shown as [Request interrupted by user] followed by that message.
• The others stay queued, and each further Esc press interrupts again and delivers the next one.
• Four queued messages cost four interruptions.
• The model answers the first message before it has seen the rest, which are corrections and follow-ups to it.

Expected

One Esc delivers every pending message together, in order, so the model reads the whole batch before acting. A message typed after the interrupt would queue normally.

#87656 asks for a setting to hold queued messages until the turn ends, and #73661 asks for one turn per queued message. Neither covers the interrupt path.
