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.

+# Collection Best Practices
+
+## Use Higher-Order Messages for Simple Operations
+
+Incorrect:
+```php
+$users->each(function (User $user) {
+    $user->markAsVip();
+});
+```
+
+Correct: `$users->each->markAsVip();`
+
+Works with `each`, `map`, `sum`, `filter`, `reject`, `contains`, etc.
+
+## Choose `cursor()` vs. `lazy()` Correctly
+
+- `cursor()` — one model in memory, but cannot eager-load relationships (N+1 risk).
+- `lazy()` — chunked pagination returning a flat LazyCollection, supports eager loading.
+
+Incorrect: `User::with('roles')->cursor()` — eager loading silently ignored.
+
+Correct: `User::with('roles')->lazy()` for relationship access; `User::cursor()` for attribute-only work.
+
+## Use `lazyById()` When Updating Records While Iterating
+
+`lazy()` uses offset pagination — updating records during iteration can skip or double-process. `lazyById()` uses `id > last_id`, safe against mutation.
+
+## Use `toQuery()` for Bulk Operations on Collections
+
+Avoids manual `whereIn` construction.
+
+Incorrect: `User::whereIn('id', $users->pluck('id'))->update([...]);`
+
+Correct: `$users->toQuery()->update([...]);`
+
+## Use `#[CollectedBy]` for Custom Collection Classes
+
+More declarative than overriding `newCollection()`.
+
+```php
+#[CollectedBy(UserCollection::class)]
+class User extends Model {}
+```
