Channel notifications from Telegram plugin not displayed in conversation

Bug Description

MCP channel notifications (notifications/claude/channel) sent by the Telegram plugin are successfully delivered but never displayed as <channel> tags in the Claude Code conversation.

Environment

• Claude Code version: 2.1.96
• Platform: macOS (Darwin 25.2.0)
• Plugin: telegram@claude-plugins-official v0.0.4
• Shell: zsh

Steps to Reproduce

1. Configure Telegram plugin with a bot token and allowlisted user
2. Start Claude Code, ensure plugin connects (/mcp shows connected)
3. Send a message from the allowlisted Telegram user to the bot
4. Expected: message appears as <channel source="telegram" ...> in the conversation
5. Actual: nothing appears — the conversation never receives the inbound message

Debugging Evidence

Added logging to the plugin's server.ts. The logs confirm:

[2026-04-08T12:39:15.897Z] polling as @unbutter_mkt_bot
[2026-04-08T12:41:22.527Z] delivering inbound from 6422572531: 테스트
[2026-04-08T12:41:22.528Z] notification delivered successfully

• bot.start() succeeds, polling is active ✅
• gate() passes (user is in allowFrom) ✅
• mcp.notification({ method: 'notifications/claude/channel', ... }) resolves without error ✅
• But the <channel> tag never appears in the conversation ❌

Additional Context

• Outbound works fine: calling mcp__plugin_telegram_telegram__reply successfully sends messages to Telegram.
• Tested with both short messages ("테스트") and long messages — neither appears.
• getUpdates API returns empty (confirming bot consumed the updates), and no 409 Conflict.
• Multiple /mcp reconnections and process restarts (pkill -f "bun.*telegram") did not resolve the issue.
• Note: system has two Claude installations (npm-global at /opt/homebrew/bin/claude and native at ~/.local/bin/claude) with a configuration mismatch warning — unclear if related.

Workaround

Currently writing inbound messages to a local JSONL file (~/.claude/channels/telegram/inbound.jsonl) and polling it via CronCreate every 2 minutes.
