vitepress-plugin-mermaid patches vitepress's client app entry,
which breaks ESM module resolution and renders all pages blank.
Replace mermaid diagrams with offset/content tables and pipeline
code blocks that render correctly.
- Wrap all enum values in backticks (FRAME, SOLID, ROUND, etc.)
- Fix single-backtick code blocks → triple backticks in node-types, scene-graph
- Replace ASCII diagrams with mermaid in file-format
- Delete stale mcp-tools.md and eval-command.md from all locales
- Update dead links: /reference/mcp-tools → /programmable/mcp-server,
/eval-command → /programmable/cli/scripting
