Description

The @openclaw/nostr plugin requires nostr-tools at runtime but doesn't declare it as a dependency. This causes the gateway to crash on startup when the Nostr channel is enabled.

Steps to Reproduce

1. Install OpenClaw: npm install -g openclaw@latest
2. Install Nostr plugin: openclaw plugins install @openclaw/nostr
3. Configure a Nostr channel in openclaw.json
4. Start gateway: openclaw gateway start

Expected Behavior

Gateway starts successfully with Nostr channel enabled.

Actual Behavior

Gateway crashes with module not found error for nostr-tools.

Workaround

Manually install nostr-tools globally:

npm install -g nostr-tools

Environment

• OpenClaw version: 2026.2.x
• Node.js: v22.x
• OS: Ubuntu 24.04

Suggested Fix

Add nostr-tools to the plugin's package.json dependencies.
