v0.13 baseline · git 初始化 + 仓库瘦身

把所有本地 demo / 测试 / 上传图 / 调试脚本搬入 local-tests/，写
.gitignore 忽略整个测试目录与 node_modules/。本次起 skill 仓库
只跟踪：SKILL.md / HANDOFF.md / PRODUCT.md / assets/（3 模板）/
references/（15 规则文档）/ agents/openai.yaml / validate-social-deck.mjs
/ package.json + lock。

历次版本（v0.1-v0.12）的全部实质改动已包含在当前文件状态中——
HANDOFF.md 的版本历史段保留作为时间轴文字记录，但代码层面以
此 commit 为唯一基线，后续逐次 commit 对应 HANDOFF.md 新增段落。

HANDOFF/PRODUCT/category-cookbook/components/style-system 中的
demo 路径引用已加 local-tests/ 前缀。SKILL.md Step 5 line 190 的
'social-card-<slug>/' 是下游用户工作区的命名约定，未改动。
