docs: add S7 PLC simulator implementation plan

- Chunk 1: Project infrastructure (solution, projects, packages)
- Chunk 2: Core enums and entities (PLC type, instance config/state)
- Chunk 3: Memory storage implementation (M/DB/I/Q/T/C regions)
- TDD approach with comprehensive unit tests
- Bite-sized tasks with exact file paths and commands

# S7 PLC模拟器实施计划

> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.

**目标:** æž„建一个基于HSL Communication库的西门子S7 PLC模拟器系统，支持多实例、Web管理界面和数据持久化。

**架构:** é‡‡ç”¨DDD分层架构，Core层实现领域逻辑，Application层提供应用服务，Server层提供Web API，Web层提供管理界面。使用HSL Communication库实现S7服务器，SignalR实现实时状态推送。

**技术栈:** ASP.NET Core 6.0, HslCommunication 12.6.3, SignalR, Razor Pages, Serilog, AutoMapper, xUnit
