--channels flag inconsistently enables/disables between launches

Description

On v2.1.81, --channels plugin:telegram@claude-plugins-official inconsistently enables or disables channels between launches with no config changes.

Behavior

• Sometimes shows: Listening for channel messages from: plugin:telegram@claude-plugins-official
• Other times shows: --channels ignored (plugin:telegram@claude-plugins-official) / Channels are not currently available
• No configuration changes between launches — same org settings, same plugin, same version

Additional Details

• When "Listening" is shown, inbound MCP notifications (notifications/claude/channel) from the plugin server are not delivered to the conversation
• Outbound tools (reply, react, edit_message) work correctly
• Plugin server is confirmed working — bot receives Telegram messages, access gate passes, typing indicator fires, notification is sent via MCP
• The server correctly declares experimental: { 'claude/channel': {} } capability

Environment

• Claude Code v2.1.81
• macOS (desktop app)
• Team Enterprise Pro plan
• Channels enabled in org admin config
• Plugin: telegram@claude-plugins-official v0.0.1
