Telegram plugin receives permission prompts triggered by unrelated MCP tools (e.g. Slack)

Bug Description

When a Slack MCP tool (e.g. slack_search_users, slack_send_message) requests permission approval in the terminal, the Telegram plugin also receives/displays the permission prompt notification — even though the action has nothing to do with Telegram.

Steps to Reproduce

1. Have both the Telegram plugin and Slack MCP server connected in the same Claude Code session
2. Trigger a Slack tool call (e.g. search for a user or send a message)
3. The terminal shows the permission approval prompt as expected
4. The Telegram plugin also shows/forwards the permission request notification

Expected Behavior

Permission prompts for Slack (or any other non-Telegram MCP tool) should only appear in the terminal where the session is running. The Telegram plugin should not receive or display these prompts.

Actual Behavior

The Telegram plugin receives and displays the permission request, even though the action was initiated from the terminal and is completely unrelated to Telegram.

Environment

• Claude Code CLI
• MCP servers: Slack + Telegram plugin both active in the same session
