Regenerate Boost guidelines and skills

Byproduct of the Laravel 13 upgrade: composer's post-update-cmd runs
`artisan boost:update`, and Boost went 2.1.3 to 2.4.x with the update.

Refreshes CLAUDE.md and boost.json for the Laravel 13 / Livewire 4 stack,
updates the livewire, pest and tailwindcss skills, replaces the
developing-with-fortify skill with fortify-development, and adds new
laravel-best-practices and octane-development skills.

Generated output, not hand-edited.

Activates when adding styles, restyling components, working with gradients, spacing, layout, flex, grid, responsive design, dark mode, colors, typography, or borders; or when the user mentions CSS, styling, classes, Tailwind, restyle, hero section, cards, buttons, or any visual/UI changes."
+description: "Always invoke when the user's message includes 'tailwind' in any form. Also invoke for: building responsive grid layouts (multi-column card grids, product grids), flex/grid page structures (dashboards with sidebars, fixed topbars, mobile-toggle navs), styling UI components (cards, tables, navbars, pricing sections, forms, inputs, badges), adding dark mode variants, fixing spacing or typography, and Tailwind v3/v4 work. The core use case: writing or fixing Tailwind utility classes in HTML templates (Blade, JSX, Vue). Skip for backend PHP logic, database queries, API routes, JavaScript with no HTML/CSS component, CSS file audits, build tool configuration, and vanilla CSS."
