refactor: Prettier 格式化全量前端、Library 服务端分页筛选、Agent 工具输出可视化与 .agent 目录统一

代码质量：
  - 新增 .prettierrc + eslint-plugin-prettier，全量格式化所有 TSX/TS/CSS 文件
  - npm scripts 新增 format / format:check / lint:fix

  Logo 重设计：
  - SVG logo 从简单星月改为望远镜+轨道+三角架+星光，favicon 同步更新

  Library 服务端分页与多维筛选：
  - LibraryQueryParams 支持 q(全局搜索)/status(下载状态)/doctype/author/year/journal/sort_by
  - API 返回 {items, total}，默认每页 12 条
  - 前端新增筛选面板：搜索栏、状态下拉、文献类型、排序、分页控件

  Agent 工具输出可视化：
  - 新增 SpecialToolRenderers.tsx：query_target 天体参数卡片(含 SIMBAD/VizieR 链接)、search_papers
  文献列表(内嵌下载/阅读/星系跳转按钮)
  - 系统内部工具(compress_context 等)无错误时自动隐藏，减少时间线噪音
  - ToolCallCard 与 Reader/Citation 打通：可在工具输出中直接打开文献或跳转引用星系

  .agent 目录统一：
  - memory/tool-results/trajectories/images 全部归入 library/.agent/ 子目录

  PDF 加载修复：
  - BilingualViewer 改用 fetch → blob:// URL 加载 PDF，绕过 iframe SameSite Cookie 限制
