Installs Chrome for Testing and the chromium-bidi server's Node deps.
Uses npx @puppeteer/browsers install to download Chrome into
.browsers/. Runs npm install in priv/bidi-server/ to fetch the
chromium-bidi Node package and its peer deps. Writes the executable
path to .browsers/PATHS so Wallabidi.BrowserPaths can find it.
Usage
mix wallabidi.install # latest stable
mix wallabidi.install 147.0.7727 # specific versionRequirements
Requires npx and npm (Node.js) to be installed. The downloaded
binaries and Node modules are cached — subsequent runs are fast.
