Telegram channel plugin: inbound notifications not surfaced in CLI

Description

The official Telegram channel plugin (telegram@claude-plugins-official) receives inbound messages from Telegram but they are never displayed in the CLI session.

Setup

• Claude Code version: 2.1.83 (latest)
• Interface: CLI (terminal)
• Platform: macOS (Darwin 23.6.0)
• Plugin: telegram@claude-plugins-official, enabled in settings.json

What works

• Plugin server starts and connects via MCP (stdio pipes confirmed)
• Outbound: telegram__reply tool successfully sends messages to Telegram users
• Bot receives inbound messages (typing indicator / ack reaction appears in Telegram)
• Gate logic passes correctly for allowlisted senders
• mcp.notification({ method: 'notifications/claude/channel', ... }) is called in server.ts

What doesn't work

• Inbound Telegram messages never appear in the CLI conversation
• The MCP notification (notifications/claude/channel) is sent by the server but not surfaced by Claude Code CLI
• Restarting sessions (tried 3+ times) does not help

Expected behavior

Messages sent by an allowlisted Telegram user should appear in the CLI conversation as <channel source="telegram" ...> blocks, as documented in the plugin's MCP server instructions.

Suspicion

The CLI may not be rendering/handling notifications/claude/channel MCP notifications. This may work in the desktop app but has not been tested there.
