feat: 升级至 v0.3.14 — 移除 AGENTS.md/USERS.md + 内置提示词统一管理 + 时间感知 + 工具管理滚动

【阶段一 · 紧急修复 F1】
- F1-1 file_editor regex 计数 bug：强制 g 标志 + 同一 RegExp 实例做 match+replace
- F1-2 code_search 统一 safeResolvePath（含路径遍历 + MEMORY.md 拦截）
- F1-3 git_commit amend 模式：message 可选 + --no-edit 防止编辑器 hang
- F1-4 write_file append 模式原子化：显式 open(O_APPEND)+write+fsync+close

【阶段二 · 增强现有工具 F2】
- F2-1 read_file 智能编码检测：BOM(UTF-8/UTF-16 LE/BE) + GBK 降级
- F2-2 read_file 支持 tail 模式（读取末尾 N 行，适用日志）
- F2-3 search_files 二进制过滤 + 智能编码检测
- F2-4 search_files 多 glob 匹配（逗号分隔，如 *.ts,*.js）
- F2-5 file_editor 新增 find_replace 操作（字面量替换，规避正则歧义）
- F2-6 file_editor regex 支持跨行匹配（multiline 参数）
- F2-7 file_editor 新增 backup 参数（编辑前 .bak 备份）

【阶段三 · 新增工具 F3】
- F3-1 file_move：双路径校验 + overwrite + 自动建父目录 + rename 原子
- F3-2 file_info：大小/时间/类型/编码/二进制/权限位

【阶段四 · 优化 F4】
- F4-1 diff_viewer Uint32Array→Uint16Array（省一半内存）+ safeResolvePath + 智能编码
- F4-2 错误处理统一：diff-viewer/file-editor/code-search catch 块改用 extractErrorMessage

【阶段五 · 验证 F5】
- tsc --noEmit 类型检查通过
- 人工审查通过：路径校验/错误处理/原子性/资源释放/权限策略/导出注册

工具数量：13 → 15（新增 file_move / file_info）
