Feature Request: Invite System for User Registration

Description:

I’d like to propose adding an invite-based registration system to Node Solid Server (NSS). This would be especially useful for small instances with limited resources, allowing admins to manage their user base more efficiently.

Why This Matters

• Resource Management: Small instances often have limited bandwidth, storage, or processing power. An invite system helps control user growth to match available resources.
• Spam Prevention: Open registration can attract spam accounts, which can be costly to moderate. An invite system ensures that new users are vetted.
• Community Building: Some deployments may prefer a curated user base, inviting only trusted individuals to maintain a specific ecosystem.

Proposed Implementation

• Admins can generate invite codes via a command-line tool or admin panel.
• Option to set invite limits (e.g., single-use, multi-use, or time-limited).
• Invite-based signups would work alongside existing registration methods (configurable in settings).

Would love to hear thoughts on feasibility and whether others would find this useful. Let me know if there’s interest, and I’d be happy to explore potential approaches!

未指定文件、测试或入口点。首先定位现有的注册流程和配置，然后确定管理面板或命令行工具如何在当前注册方式之外生成单次使用、多次使用或限时邀请。范围和配置行为得到定义并由适当的测试覆盖后，即视为完成。
