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.
