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 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
