[Bug] Plugin TUI validation rejects agents array while CLI install succeeds

Plugin TUI installation fails validation but one-shot command works

Description:

• Plugin with agents array fails validation in /plugin TUI menu with "agents: Invalid input"
• Same plugin installs successfully via one-shot command /plugin install plugin-name@marketplace
• All TUI installation scope options (user, project, local) produce the error
• One-shot command works for all scopes

Reproduction:

1. Create plugin with agents array in plugin.json
2. Try to install via /plugin → Browse → Select plugin → Any install option → Error
3. Install via /plugin install react-native-dev-team@rad-cc-plugins → Success

Plugin manifest that fails TUI but works CLI:

  {
    "name": "react-native-dev-team",
    "version": "1.1.10",
    "description": "React Native and Expo development toolkit",
    "author": { "name": "Tobey Forsman" },
    "agents": [
      {
        "name": "react-native-engineer",
        "source": "./agents/react-native-engineer.md",
        "description": "React Native & Expo engineer"
      }
    ]
  }
