Description

[Description]
The /nemoclaw slash command registered by the NemoClaw plugin cannot be executed inside the OpenClaw TUI. Typing /nemoclaw in the chat input
produces no response and no autocomplete/command hints. The plugin defines subcommands (status, shields, config, etc.) but none are reachable
from the TUI.

[Environment]
Device: Ubuntu 22.04 (Linux 5.15.0-171-generic)
Node.js: v22.22.2
npm: 10.9.7
Docker: Docker Engine 29.4.0
OpenShell CLI: openshell 0.0.26
NemoClaw: v0.0.18
OpenClaw: 2026.4.2 (d74a122)

[Steps to Reproduce]

1. Launch sandbox TUI:
   nemoclaw my-assistant connect
   openclaw tui

2. In the TUI chat input, type:
   /nemoclaw

3. Press Enter.

[Expected Result]

• Typing /nemoclaw should show autocomplete hints for available subcommands (status, shields, config, etc)
• Pressing Enter should execute the command or display help output

[Actual Result]

• No autocomplete or command hints appear
