pasting issue

Describe the bug

Bug: Pasted multi-line content not sent to model

Environment: WezTerm (Ctrl+V →  PasteFrom "Clipboard" ) on Windows, running Copilot CLI inside WSL (zsh). CLI version 1.0.80.

Expected: The full pasted content (12 lines) is sent to the model as part of the message.

Actual: The model responds as if no content was received — e.g., "I don't see the pasted content — it looks like it didn't come through." The paste token is not being expanded/substituted with the real content before the request is sent.

Notes: Terminal/paste mechanism itself works correctly (bracketed paste, WezTerm config verified clean) — this appears to be a CLI-side bug in how paste tokens are resolved before submission.

Affected version

GitHub Copilot CLI 1.0.80.

Steps to reproduce the behavior

Steps to reproduce:
in wezterm using wsl,

1. Copy multi-line text (e.g., 12 lines) to clipboard.
2. Prompt correctly shows a collapsed token:  [Paste #1 - 12 lines] .
3. Press Enter to submit.

Expected behavior

No response

Additional context

No response

Reproducir en WezTerm en Windows con Copilot CLI dentro de WSL usando zsh, copiar 12 líneas y enviar el token [Paste #1] contraído. Como no se nombra ningún archivo fuente ni ninguna prueba, rastrear el manejo del token de pegado desde el envío del prompt hasta la solicitud al modelo. Se considera terminado cuando el contenido completo pegado está incluido en el mensaje enviado.
