Adds packages/plugin-sandbox: QuickJS-ng compiled to wasm, running in a dedicated worker, with a runtime shell inside it that loads a plugin bundle and answers the same InternalEventPayload events the Node runtime answers. Plugins are unmodified. Wires the browser host's template function, authentication, cURL import and template render commands to it, and relaxes TemplateCallback's Send bound on wasm32 so the engine's renderer can call back out to a plugin.

|
* Bundle the guest shell into a string the host can evaluate.
|
|
*
|
|
* The shell runs inside QuickJS, which has no module loader and no filesystem,
|
|
* so it has to arrive as source text. Emitting it as a `.ts` module rather than
|
|
* a `.js` asset is what lets every consumer — Vite for the browser build, plain
|
|
* Node for the benchmarks — get at it the same way, with no loader plugin and
|
|
* no `?raw` import that only one bundler understands.
|
|
*
|
|
* The output is committed, like the wasm packages are, so a checkout builds
|
|
* without this step having run.
