This commit introduces a new `/members` page to display a directory of alumni association members.
- Member data is sourced from a CSV file (`content/members/members.csv`) and managed via Nuxt Content.
- The page presents member information in a table, including calculated graduation class (`届别`).
- A link to the new page has been added to the main navigation.
- Minor UI tweaks and data corrections in other sections are also included.
This commit adds two draft documents for the official website launch presentation. These files outline the structure, key messages, and content for the slides.
- `PPT Designs v1.md`: Provides a standard presentation structure covering the project's goals, features, and roadmap.
- `PPT Designs v2.md`: Offers a more refined narrative focusing on value, contribution, and open-source aspects, including copy for press releases and announcements.
