Adds checking of plugin compatibility

[JhonathanLepidus]

This pull request adds a plugin compatibility check before installation or update.

Thus, each plugin must specify in its version.xml file which applications and their respective versions it is compatible with (from 3.6 and beyond).

This is done through a new node called “compatibility.” It works similarly to the method used in the plugin gallery to indicate plugin compatibility.

Example of version.xml of a plugin compatible with OJS and OPS versions 3.6.0-x:

<version>
	<application>pluginTemplate</application>
	<type>plugins.generic</type>
	<release>1.0.0.0</release>
	<date>2023-05-15</date>
 	<class>PluginTemplatePlugin</class>
 	<compatibility application="ojs2">
		<release>~3.6.0.0</release>
	</compatibility>
 	<compatibility application="ops">
		<release>~3.6.0.0</release>
	</compatibility>
</version>

This pull request addresses a feature requirement described in the issue #7531 and was implemented in the context of the 2026's Plugin Sprint :)

Just a few minor comments -- these should be applied to the stable-3_5_0 PR too, please! Feel free to take or leave the stylistic suggestions; they are not important.

This is just stylistic, but unless the self-doc adds something, it's best to just use a typehint.

Suggested change

	/**
	* Checks whether the given plugin version is compatible with the current application version.
	*
	* @param array $versionInfo
	*
	* @throws Exception if the plugin version is not compatible
	*/
	public static function checkPluginVersionCompatibility($versionInfo): void

I think you'll need to prevent a warning here when there are none for this application:

Suggested change

	$compatibleVersions = $compatibility[$application->getName()];
	$compatibleVersions = $compatibility[$application->getName()] ?? [];

(Never mind, I see this is checked above)

Just stylistic, but you can use an early return:

Suggested change

	$hasCompatibleVersion = false;
	foreach ($compatibleVersions as $compatibleVersion) {
	if ($applicationVersion->isCompatible($compatibleVersion)) {
	$hasCompatibleVersion = true;
	break;
	}
	}
	if (!$hasCompatibleVersion) {
	throw new Exception(__('manager.plugins.incompatiblePlugin.version'));
	}
	foreach ($compatibleVersions as $compatibleVersion) {
	if ($applicationVersion->isCompatible($compatibleVersion)) {
	return; // A compatible version was found
	}
	}
	// There was no compatible version found.
	throw new Exception(__('manager.plugins.incompatiblePlugin.version'));
