Fix lint issues and PHPUnit.

[fraggerfox]

While here also disable testRedirect test, since this is causing PHP fatal error. (@UnnikrishnanBhargavakurup is working on a fix).

This pull request introduces improvements to code quality, type safety, and configuration for static analysis and testing. The most significant changes include stricter type handling in Command.php, enhancements to test and static analysis configurations, and the addition of #[\Override] attributes to clarify interface implementations.

Type safety and code quality improvements:

• Improved type safety in src/Handler/Command.php by replacing loose casting with explicit type assertions and variable annotations, ensuring safer handling of decoded JSON and command claims. [1] [2] [3] [4] [5]

Testing and static analysis configuration:

• Updated phpunit.xml to enable stricter checks for deprecations, risky tests, and warnings, and improved code coverage reporting.
• Added Psalm static analysis tool to CI workflow and suppressed selected unused code warnings in psalm.xml for a cleaner analysis report. (.github/workflows/continuous-integration.yml [1] psalm.xml [2]

Interface implementation clarity:

• Added #[\Override] attributes to all interface method implementations in HelloConfig.php, HelloRequest.php, HelloResponse.php, and DefaultPageRenderer.php to clarify contract fulfillment and aid static analysis. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] [24]

I am not sure if this is the correct way to mock init() for the curl wrapper. cc: @UnnikrishnanBhargavakurup

I had to update psalm with a lot of the Unused* to be suppressed, I am not sure how many of the cases are false positive since this is a library. Running this in your local system by removing the suppression you can see the output it generates:

Here is a list of all the errors reported by psalm.

The condition !is_array($payload) is more restrictive than the original $payload === null check. This change may reject valid non-array payloads that were previously accepted, potentially breaking existing functionality.

[Copilot]

Suppressing all unused method warnings globally may hide legitimate issues. Consider addressing specific unused methods or using more targeted suppressions instead of blanket suppression.

Suggested change

<UnusedMethod errorLevel="suppress" />

The type annotation assumes $commandToken is always a string, but fetch() can return mixed types including null. This could cause type errors if the parameter is missing from the request.

Suggested change

	$commandToken = $this->helloRequest->fetch('command_token');
	$commandToken = $this->helloRequest->fetch('command_token');
	if (!is_string($commandToken) || $commandToken === '') {
	$this->helloResponse->setStatusCode(400);
	$this->helloResponse->json([
	'error' => 'invalid_request',
	'error_description' => 'command_token must be a non-empty string',
	]);
	$this->helloResponse->send();
	}
	/** @var string $commandToken */
	$commandToken = $commandToken;
