feat(logger): Implement custom logger injection for Typesense client

[jkobus]

Change Summary

The Typesense PHP client now supports injecting your own PSR-3 compatible logger instance instead of using the default Monolog logger.

Usage

With Custom Logger

You can pass any PSR-3 compatible logger instance via the logger configuration option:

use Monolog\Logger;
use Monolog\Handler\StreamHandler;
use Typesense\Client;

// Create your custom logger
$customLogger = new Logger('my-app');
$customLogger->pushHandler(new StreamHandler('/var/log/typesense.log', Logger::DEBUG));

// Pass it to the client
$client = new Client([
    'api_key' => 'xyz',
    'nodes' => [
        [
            'host' => 'localhost',
            'port' => '8108',
            'protocol' => 'http',
        ],
    ],
    'logger' => $customLogger,  // Your custom logger
]);

Compatible Loggers

Any PSR-3 compliant logger will work:

• Monolog
• Symfony Logger
• Laravel Logger
• Any other PSR-3 compliant implementation

Default Behavior

If you don't provide a custom logger, the client will create a default Monolog logger that writes to stdout:

$client = new Client([
    'api_key' => 'xyz',
    'nodes' => [
        [
            'host' => 'localhost',
            'port' => '8108',
            'protocol' => 'http',
        ],
    ],
    'log_level' => Logger::INFO,  // Optional: customize the default logger level
]);

Implementation Details

The change was made in src/Lib/Configuration.php:

// Allow custom logger injection
if (isset($config['logger']) && $config['logger'] instanceof LoggerInterface) {
    $this->logger = $config['logger'];
} else {
    $this->logLevel = $config['log_level'] ?? Logger::WARNING;
    $this->logger   = new Logger('typesense');
    $this->logger->pushHandler(new StreamHandler('php://stdout', $this->logLevel));
}

This ensures backward compatibility - existing code will continue to work without any changes.

Example

See examples/custom_logger.php for a complete working example.

No worries if that was the case, I just feel like AI reviews tend to bring visual noise with them and didn't want them start reviewing every PR out of nowhere haha

Added InvalidArgumentException when trying to set logger to something else than \Psr\Log\LoggerInterface; also, configuration will throw an exception when log_level option is used together with logger - it would be ignored anyway.
