feat: Set up GoodAction Hub standalone data repository

[Copilot]

Repurposes this repo from "Fake Open Source wiki" into the GoodAction Hub independent data repository, migrating the data structure documentation from GoodAction-Hub.github.io and establishing an Issue-based data submission workflow.

Issue Templates

• Renamed Fake-Open-Source-event.yml → activity.yml: rebuilt as a unified public welfare activity submission form covering meetups, conferences, and competitions
• Added a type dropdown (meetup / conference / competition) to replace the need for three separate templates
• Issue title serves as the activity title; submission guidelines explain the automated PR → review → merge → website pipeline
• Added start_time and end_time fields (YYYY-MM-DD HH:mm:ss) for overall activity duration; timeline textarea (Markdown table format, pre-filled as default value) retained for per-session key milestones
• Removed year field, human-readable date field (view layer concern), and redundant confirmation checkbox
• Removed conference.yml and competition.yml (merged into activity.yml)
• Added restaurant.yml: new submission form for accessibility-friendly restaurants, with fields for unique ID, description, accessibility features, specialty food (Markdown table of dish name + price), average spend, social values (checkboxes), address, and GPS coordinates

README

• Unified "如何添加数据 / How to Add Data" section (activity + restaurant) with a single common description and beginner-friendly hint pointing to both submission links
• "数据结构 / Data Structure" section with two subsections: ### 活动 / Activities and ### 餐厅 / Restaurants
• Link references renumbered sequentially: [1]=提交活动, [2]=提交餐厅, [3]=审核列表, [4]=JSON API
• 灵感来源 / Inspiration section links to BiYuanShe/Fake-Open-Source-wiki (the template repository)
• Activity YAML schema includes both start_time/end_time and timeline with deadline/comment entries; restaurant YAML schema includes food[].name/price, avg_spend, and social_values array

GitHub Actions

• submit-event.yml: Renamed to "Activity submission"; updated label trigger (event → activity), template path (activity.yml), and all environment variable names to match new form fields
• save-event.sh: Fully rewritten to append structured entries to data/activities.yml; uses shared append_yaml_table from yaml_utils.sh to parse the timeline Markdown table into YAML deadline/comment entries
• submit-restaurant.yml: New workflow triggered by restaurant label; parses restaurant form fields and appends entries to data/restaurants.yml
• save-restaurant.sh: New script that uses shared append_yaml_table from yaml_utils.sh to parse the food Markdown table into food[].name/price entries, plus append_yaml_split_array for comma-separated features and checkboxes
• yaml_utils.sh: New shared utility module containing yaml_escape, append_yaml_split_array, and the generic append_yaml_table function (parses any 2-column Markdown table into a YAML list with configurable key names, indentation, and header-row detection); sourced by both save scripts
• deploy-data.yml: Fixed stale biyuanshe.github.io/Fake-Open-Source-wiki URL → goodaction-hub.github.io/GoodAction-data

Data Directory

• data/events.yml → data/activities.yml (empty, to be populated during future data migration)
• data/competitions.yml and data/conferences.yml deleted (all activities consolidated into activities.yml)
• Added empty data/restaurants.yml

Repository Labels (settings.yml)

Replaced event label with activity, conference, competition; added restaurant label.

给 activity 表单增加一项“类型”下拉框，选项分别为 meetup、 conference、competition，这样就可以把三个表单合为一个，因为其它项都是一样的。

给 activity 表单增加一项“类型”下拉框，选项分别为 meetup、 conference、competition，这样就可以把三个表单合为一个，因为其它项都是一样的。

已在 2fedd18 中实现：删除了单独的 conference.yml 和 competition.yml，并在 activity.yml 中添加了"活动类型"下拉框，选项为 meetup、conference、competition。

数据结构来源仓库的美食数据 也需要遵照同样的模式，来实现收集表单和数据解析工作流。

[Copilot]

数据结构来源仓库的[美食数据](https://github.com/GoodAction-Hub/GoodAction-Hub.github.io/blob/main/README.md#%E5%A6%82%E4%BD%95%E6%B7%BB%E5%8A%A0%E7%BE%8E%E9%A3%9F%E5%9C%B0%E6%97%A0%E9%9A%...

已在 4a61892 中实现：

1. .github/ISSUE_TEMPLATE/restaurant.yml：新增餐厅提交表单，字段包括唯一 ID、简介、无障碍特色服务（逗号分隔）、特色美食、社会价值、地址、GPS 纬度/经度；餐厅官方名称作为 Issue 标题。
2. data/restaurants.yml：新建空的餐厅数据文件。
3. .github/scripts/save-restaurant.sh：新增解析脚本，将表单字段写入 data/restaurants.yml，features 字段按逗号拆分为 YAML 数组。
4. .github/workflows/submit-restaurant.yml：新建工作流，由 restaurant label 触发，解析表单字段并自动创建 PR。
5. settings.yml：新增 restaurant label。
6. README.md：功能入口新增"提交餐厅"链接，新增餐厅数据说明节与数据结构示例。
