The render tool needs esbuild to transform JSX → createElement calls, but
esbuild only runs in Node, not in the browser where the automation server
executes commands. The bridge now:
1. Intercepts render tool calls with JSX
2. Uses Vite's ssrLoadModule to import @open-pencil/core (handles TS source)
3. Transforms JSX → tree on the Node side via buildComponent + resolveToTree
4. Sends the tree to the browser which calls renderTreeNode directly
Also fixes @open-pencil/core exports: remove "node" condition that pointed
to non-existent dist/ during development. Published consumers get dist/ via
publishConfig.exports override.
Bun picks the "node" condition pointing to dist/index.js which doesn't
exist in CI or fresh checkouts. Explicit "bun" condition ensures Bun
always resolves to source files.
Move engine (scene-graph, renderer, layout, codec, kiwi) into
packages/core/ as a Bun workspace package. The app's src/engine/
files become thin re-export shims so all existing imports still work.
- Bun workspace with packages/core
- Zero DOM dependencies in core
- Headless-friendly CanvasKit init (locateFile option)
- Constants split: engine constants in core, UI constants in app
- All 76 unit tests pass, lint + typecheck clean, vite build works
