Telegram plugin: inbound messages not forwarded to session

Description

The Telegram plugin (telegram@claude-plugins-official v0.0.4) receives inbound messages via polling but does not forward them into the Claude Code session.

Environment

• Claude Code on macOS (Darwin 25.3.0, Apple Silicon)
• bun v1.3.11
• Plugin version: 0.0.4

Steps to Reproduce

1. Install the Telegram plugin: /plugin install telegram@claude-plugins-official
2. Configure bot token in ~/.claude/channels/telegram/.env
3. Complete pairing (access.json shows user in allowFrom)
4. /reload-plugins — MCP server connects successfully
5. Send a message to the bot in Telegram

Expected Behavior

The message should appear in the Claude Code session as a <channel source="telegram" ...> notification.

Actual Behavior

• The message is consumed by the bot's getUpdates polling (confirmed: getUpdates returns empty after sending)
• No message or notification appears in the Claude Code session
• Outbound replies via mcp__plugin_telegram_telegram__reply work correctly — the bot can send messages to the user

Additional Observations

• getMe confirms bot token is valid and polling is active
• getWebhookInfo shows no webhook conflict
• MCP tools (reply, react, edit_message) are all available and functional
• /reload-plugins consistently reports 0 skills despite valid user-invocable: true SKILL.md files in the plugin's skills/ directory (possibly a separate issue)
• Process is running and stderr shows telegram channel: polling as @<botname> with no errors
