Before creating, modifying, or troubleshooting Notion as Code code, read
node_modules/@notionhq/apps/skills/notion-as-code/SKILL.md.
Resolve this path relative to the App project root.
Follow the instructions in that file.
If the file is missing, install the project dependencies.
If it remains missing, update @notionhq/apps to a release that includes the skill.
Do not continue with Notion as Code changes until you can read the SDK skill.
