Pull request overview

This PR refreshes several user-facing documentation pages for ShanghaiTech’s handbook to reflect campus services and structures as of 2025–2026, and introduces a new “学在科大” academic guide. The changes expand content for new students, clarify services like self-service printing and software licensing, and improve navigation between guide sections.

Changes:

• Updated existing pages (home, life, surroundings, skills, fresh, fresh/preparations) with current information on dining, campus services, medical care, military training, and printing.
• Added a new academic page that centralizes guidance on course selection, GPA rules, scholarships, and exchange/research opportunities, and wired it into navigation.
• Introduced a basic .gitignore to exclude editor-specific and OS-specific artifacts.

File	Description
surroundings.md	Updated campus surroundings info to mention Manner 咖啡; note: current line mixes an inline note with a stray pipe, slightly breaking Markdown formatting.
skills.md	Extended “服务与技巧” with sections on licensed software and detailed self-service printing instructions (fees, registration, client setup, and usage); also contains a minor typo in the name of the Aegis authenticator app.
life.md	Replaced placeholder content with structured guidance on food, payments/repairs, medical care/insurance, and express/printing; printing description links to skills but currently uses terminology (“PaperCut”) that’s not aligned with that page.
home.md	Updated metadata date and added a “快速入口” section that links to key handbook pages, including the new academic and life pages.
fresh/preparations.md	Added an “体检与军训” section to brief new students on entrance medicals and undergraduate military training.
fresh.md	Updated metadata date and added a link to the new academic guide from the “初来乍到” landing page.
academic.md	New page outlining course selection phases and credit limits, GPA conversion rules, major scholarship types, exchange/summer research opportunities, and lab/innovation programs.
.gitignore	Added ignores for .vscode/ and .DS_Store to keep local/editor files out of version control.

这一行在括号后接了「| 2025 年起，校内已引入 Manner 咖啡等多家连锁品牌。」且与前文在同一行，竖线会被当作普通字符渲染，整体排版不自然。建议去掉竖线，将「2025 年起……」拆成独立句（或单独一行/段落）说明背景信息，以提升可读性。

「Ageis」应为 2FA 应用名称「Aegis」，当前拼写有误，可能影响搜索或理解。建议将该处拼写从「Ageis」修正为「Aegis」。

	首先你需要配置多因素认证，通常情况下你需要使用备用邮箱、手机号以及下载软件来认证。为此，GeekPie 社团编写了 [ShanghaiTech-Mail-TOTP](https://github.com/ShanghaitechGeekPie/ShanghaiTech-Mail-TOTP?tab=readme-ov-file) 项目，当你安装了油猴插件时可以使用此插件，将 APP 认证改为普通的 TOTP 方式。从而让你能够导入到例如 Ageis，Google Authenticator 等软件中。

这里说明「全校自助打印点支持 PaperCut 系统」，但链接到的「服务与技巧」页面中，自助文印部分统一使用的是「易安 (esafe) 自助打印复印系统」的称呼，未解释二者关系，可能让读者误以为是两个不同系统。建议统一用语（例如统一称为自助文印系统）或在任一页面补充说明 PaperCut 与易安/自助文印系统之间的关系，以避免歧义。
