Fix AddMissingVarNameFixer to handle intersection types in @var

[TomasVotruba]

Problem

AddMissingVarNameFixer skipped inline @var annotations with an intersection type:

/** @var MockObject&AbstractIntegration */
/** @phpstan-ignore classConstant.deprecatedClass */
$integration = $this->getMockBuilder(AbstractIntegration::class);

The variable name was never filled in.

Cause

VAR_WITHOUT_NAME_REGEX type char class [\\\\\w\|\[\]-]+ had no &, so intersection types failed to match. (The second docblock line below is not the blocker — getNextMeaningfulToken already skips it; a simple type with a docblock underneath fixed fine.)

Fix

Add & to the type char class. Now the annotation becomes:

/** @var MockObject&AbstractIntegration $integration */

New fixture intersection_type_with_docblock_below.php.inc covers the exact reported case.

phpstan / rector / ecs / phpunit all green.
