Describe the bug

Code snippets starting with // cause Unknown command: // in GitHub CLI

Description

When pasting code into the GitHub CLI, any snippet that begins with // triggers an error:

✗ Unknown command: //

Example:

// this prints hello
print("hello")

The CLI interprets // as a command instead of treating it as literal text. This makes it difficult to paste code examples that use // comments unless the user manually wraps everything in triple‑backtick fences.

Expected behavior

// inside pasted text should be treated as literal content when entering issue or PR text.

Actual behavior

The CLI attempts to execute // as a command and returns:

✗ Unknown command: //

Steps to reproduce

1. Paste a snippet starting with //.
2. Observe the error.

Affected version

GitHub Copilot CLI 0.0.403.
