Pull request overview

This PR updates the build/test tooling around Lexxy’s browser tests and asset bundling, and adds a precompressed Brotli asset for the minified bundle.

Changes:

• Configure Playwright to use system Chromium/Firefox executables when present.
• Mark @rails/activestorage as an external dependency in the Rollup build.
• Add a Playwright npm script intended to run browser tests without WebKit, and add lexxy.min.js.br to assets.

launchOptions is always being set, and when the executable path isn't present it becomes an empty object. That can unintentionally override any default/device launchOptions (or any future shared use.launchOptions) with {}. Prefer omitting launchOptions entirely when no override is needed (e.g., set it to undefined or conditionally spread it).

	...devices["Desktop Chrome"],

	} },
	{ name: "firefox", use: {
