npm Plugin Support

What: Claude Code now supports loading plugins directly from npm packages using the npm: prefix in repository names

How to use:

# In your settings.json, add npm packages as plugin repositories
{
  "enabledPlugins": {
    "npm:@claude/example-plugin": true,
    "npm:claude-dev-tools": ["specific-command"]
  }
}

Details:

• Package names must follow npm naming conventions (alphanumeric, hyphens, periods, underscores)
• Supports both regular and scoped npm packages (e.g., @org/package-name)
• Automatically resolves packages from node_modules directory
• Validates plugin structure (requires commands/, agents/, plugin.json, or hooks/ directories)
