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

Reproduce in WezTerm on Windows with Copilot CLI inside WSL using zsh, copying 12 lines and submitting the collapsed [Paste #1] token. No source file or test is named, so trace the paste-token handling from prompt submission to the model request. Done means the full pasted content is included in the submitted message.
