Issue: /copy fails even after successful model output

Environment:

• Codex CLI version: 0.116.0
• OS: Ubuntu (remote)
• Access method: SSH into remote machine
• Terminal: (fill in if known, e.g. bash / zsh / tmux)

Reproduction steps:

1. Start a fresh Codex CLI session
2. Enter a simple prompt: hi
3. Wait until the model output fully completes and CLI is idle
4. Run /copy

Expected behavior:

• /copy should copy the latest completed model output

Actual behavior:

• Error message:

/copy is unavailable before the first Codex output or right after a rollback

Notes:

• The model output is clearly visible and completed before running /copy
• No rollback or undo actions were performed
• This worked correctly in earlier Codex CLI versions (regression)
• Issue is reproducible consistently

Additional context:

• Running entirely in a remote SSH session (no local GUI clipboard)
• Unsure if related to TUI state sync or SSH environment handling
