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.

+# Configuration Best Practices
+
+## `env()` Only in Config Files
+
+Direct `env()` calls may return `null` when config is cached.
+
+Incorrect:
+```php
+$key = env('API_KEY');
+```
+
+Correct:
+```php
+// config/services.php
+'key' => env('API_KEY'),
+
+// Application code
+$key = config('services.key');
+```
+
+## Use Encrypted Env or External Secrets
+
+Never store production secrets in plain `.env` files in version control.
+
+Incorrect:
+```bash
+
+# .env committed to repo or shared in Slack
+
+STRIPE_SECRET=sk_live_abc123
+AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI
+```
+
+Correct:
+```bash
+php artisan env:encrypt --env=production --readable
+php artisan env:decrypt --env=production
+```
+
+For cloud deployments, prefer the platform's native secret store (AWS Secrets Manager, Vault, etc.) and inject at runtime.
+
+## Use `App::environment()` for Environment Checks
+
+Incorrect:
+```php
+if (env('APP_ENV') === 'production') {
+```
+
+Correct:
+```php
+if (app()->isProduction()) {
+// or
+if (App::environment('production')) {
+```
+
+## Use Constants and Language Files
+
+Use class constants instead of hardcoded magic strings for model states, types, and statuses.
+
+```php
+// Incorrect
+return $this->type === 'normal';
+
+// Correct
+return $this->type === self::TYPE_NORMAL;
+```
+
+If the application already uses language files for localization, use `__()` for user-facing strings too. Do not introduce language files purely for English-only apps — simple string literals are fine there.
+
+```php
+// Only when lang files already exist in the project
+return back()->with('message', __('app.article_added'));
+```
