feat: Phase1 项目骨架 - Maven项目结构、核心AgentLoop、6个工具、命令系统、控制台渲染、REPL会话

实现内容:
- pom.xml: JDK25 + Spring AI 2.0.0-M4 + JLine3 + Picocli
- core/AgentLoop: 基于ChatModel的显式工具循环(非ChatClient)
- tool/: Tool接口 + ToolRegistry + ToolCallbackAdapter(适配Spring AI)
- tool/impl/: BashTool, FileReadTool, FileWriteTool, FileEditTool, GlobTool, GrepTool
- command/: SlashCommand接口 + CommandRegistry + /help, /clear, /exit
- console/: AnsiStyle, BannerPrinter, ToolStatusRenderer, ThinkingRenderer, SpinnerAnimation, MarkdownRenderer
- context/: SystemPromptBuilder, ClaudeMdLoader(多级CLAUDE.md加载)
- repl/ReplSession: REPL主循环(Scanner降级方案)
- config/AppConfig: Spring Bean装配
- application.yml: Anthropic/OpenAI双模型配置
