✨ feat: add project catalog for lab and docs

[zrr1999]

动机

把 Lab、中央文档和产品官网的边界定成仓库约定。小项目从 Lab 进入，公开文档从 docs.zrr.dev 发布；产品官网在项目侧独立演进，购买专有域名时只改入口。

解决方案

• 在 docs/platform.md 写下三阶段。小项目使用 lab.zrr.dev/<project>/ 和 docs.zrr.dev/<project>/。产品化后官网迁到项目侧，<project>.zrr.dev/docs 跳到中央文档并保留章节路径。专有域名阶段，旧子域名整站跳到新入口，官网可以留在代码仓库，也可以放在所属组织下的单独网站仓库。
• 增加 packages/project-catalog。每个项目一份 TOML，推导 Lab、文档和官网地址，并生成 zrr.dev 域名上的 308 跳转。
• 按当前事实登记 Cue、Spark、Zendev、Rill 和 Spore。lab.zrr.dev 与 docs.zrr.dev 尚未部署，跳转规则也还没有发到 Cloudflare。

说明

文档权威地址在三个阶段都是 docs.zrr.dev/<project>/。产品站和专有域名上的 /docs 是入口，不是第二套文档站。

Rill 的文档站目前占用 rill.zrr.dev。docs.zrr.dev/rill/ 提供相同页面前，不要部署这条旧主机跳转。Spore 官网已经在 spore-lang/spore-lang.dev，文档仍由 docs.spore-lang.dev 发布，接入中央文档前不登记构建方式。

首页项目列表仍在 apps/root。Lab 接管目录之前，调整已登记项目的对外摘要时，登记表和首页一起改。

后续工作

• 增加 apps/lab 与 apps/docs。先接入 Zendev，走通获取源码、子路径构建、编辑链接和旧主机跳转，再接入 Rill。
• 公开文档逐个切到 docs.zrr.dev/<project>/ 后，再关闭原来的文档发布并保留旧地址跳转。
