feat: add support for Laravel 13, Livewire 4, and PHP 8.5

[epessine]

Adds additive compatibility for Laravel 13, Livewire 4, and PHP 8.5 while keeping full backward compatibility with Laravel 10–12, Livewire 3, and PHP 8.2–8.4.

Changes

Laravel 13

• Updated laravel/framework constraint to ^10.0|^11.0|^12.0|^13.0
• Updated orchestra/testbench to ^8.0|^9.0|^10.0|^11.0

Livewire 4

• Updated livewire/livewire constraint to ^3.0|^4.0
• Updated pestphp/pest-plugin-livewire constraint to ^2.1|^4.0
• Fixed runtime incompatibility: Livewire 4 treats :: in component names as a namespace separator. Renamed the axis::renderer component alias to axis-renderer in AxisServiceProvider and RendersAsChart.

PHP 8.5

• Extended php constraint from ^8.2|^8.3|^8.4 to ^8.2|^8.3|^8.4|^8.5
• Added 8.5 to the CI test matrix
• Updated formats workflow to run on PHP 8.5
• Updated README compatibility section

Pest

• Updated pestphp/pest constraint to ^2.34|^3.5|^4.3

Style fixes (Pint)

• Added declare(strict_types=1) to RendersAsFile, tests/Helpers.php, and tests/Pest.php
• Replaced FQCNs with imported class names to satisfy fully_qualified_strict_types rule
• Added (string) cast on str() return in RendersAsFile to satisfy the declared : string return type
