Scaffold the Livewire Material package

The skeleton for nonameweb/livewire-material: service provider and config
(unprefixed components, blade-icons' own <x-icon> switched off, an opt-in
showcase at /material), the Testbench Workbench with its Vite build, the
CSS and JS entry points applications import, the Boost guideline and skill
with a drift test, and Gitea CI running Pint, feature tests on PHP 8.4 and
8.5, and browser tests in Chrome, Firefox and Safari.

The plan moved here from SealShare: docs/plans/livewire-material.md.
