Add help command to display script capabilities

[Copilot]

The script lacked a direct way for users to discover its capabilities. When asked "你能做什么" (what can you do?), users had to browse code or rely on external documentation.

Changes

• Added k_help() function: Displays bilingual (CN/EN) overview of 8 feature categories (system management, Docker, LDNMP, networking, security, app marketplace, server tools, game servers)

• Command handlers: help, --help, -h, 帮助, 你能做什么 all invoke help

• Updated k_info(): Added help command as first reference example

Usage

$ k 你能做什么
======================================

【核心功能 / Core Features】

1. 系统管理 / System Management
   • 系统信息查询 - 查看CPU、内存、磁盘、网络等
   ...

$ k help  # Same output
$ k --help  # Same output

Help text provides feature overview; unknown commands trigger usage examples via k_info() to avoid circular documentation.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.kejilion.pro
  • Triggering command: /usr/bin/curl curl -s -X POST REDACTED -H Content-Type: application/json -d {"action":"������������","timestamp":"2026-02-04 01:43:56","country":"","os_info":"Ubuntu 24.04.3 LTS","cpu_arch":"x86_64","version":"4.3.8"} (dns block)

• v6.ipinfo.io
  • Triggering command: /usr/bin/curl curl -s --max-time 1 REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
