JLine 3 集成: - ReplSession重写: JLine Terminal + LineReader 替代Scanner - 支持行编辑（光标移动、删除、Home/End等） - 持久化历史记录（~/.claude-code-java/history） - 上下箭头浏览输入历史 - Ctrl+C取消当前输入、Ctrl+D退出 - JLine失败时自动降级到Scanner模式 Tab补全: - ClaudeCodeCompleter: 斜杠命令补全（/后按Tab） - 支持命令别名补全（如 /q → exit） - 分组显示（Commands / Aliases） 新增命令: - /model: 显示当前AI模型信息 - /compact: 压缩对话上下文 - /cost: Token用量显示（占位） 改进: - HelpCommand清理为统一格式 - Banner增加终端信息显示和快捷键提示 - 彩色提示符使用AttributedStringBuilder Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>pull/1/head
