	forceMessagePortWorkerComms bool,
) (*BrowserBundleResult, error)

BuildBrowserBundle builds and outputs the web & service worker files.

stateDir is the directory where bun will be downloaded if not found in PATH. webStartupSrcPath is the path to the startup js module to load for the react app entrypoint (can be empty). entrypointHash, if set, builds into /entrypoint/{entrypointHash}/...

type BuildManifest 

type BuildManifest struct {
	Entrypoint            string                 `json:"entrypoint"`
	ServiceWorker         string                 `json:"serviceWorker"`
