Discord reply blocked after answering permission prompt via Discord

Bug Description

When a tool call requires user permission approval and the user responds to the permission prompt via Discord (instead of the CLI terminal), subsequent reply tool calls to the Discord channel are blocked/fail silently.

Steps to Reproduce

1. Claude Code is running with Discord channel plugin
2. A tool call triggers a permission confirmation prompt (e.g., file edit, bash command)
3. User approves the permission via Discord message (instead of pressing 'y' in the CLI)
4. After permission is granted, the assistant attempts to send a Discord reply
5. The reply is blocked or fails

Expected Behavior

After permission approval (regardless of how it was granted), Discord reply tool calls should work normally.

Actual Behavior

Discord reply calls are blocked after permission was approved via Discord message. The assistant cannot send further messages to the Discord channel until the session is refreshed or a new turn begins.

Environment

• Claude Code CLI (latest)
• Discord channel plugin (plugin:discord:discord)
• Platform: Linux (WSL2)
