✨ feat: 初始化飞拍替换方案仓库骨架

* 建立 .NET 8 解决方案及分层项目结构
* 添加 Flyshot.Core.Domain 领域模型（机器人、轨迹、运动学）
* 添加 Flyshot.Core.Planning 规划层（ICSP、CubicSpline、采样器）
* 添加 Flyshot.Core.Triggering 触发时序与 IO 时间轴
* 添加 Flyshot.Core.Config 配置兼容与 .robot 解析
* 添加 Flyshot.Server.Host 最小宿主及 /healthz 端点
* 补充单元测试与集成测试项目
* 添加 CLAUDE.md、AGENTS.md、README.md 项目规范
