📋 PR Summary

This PR fixes PHPStan errors on the 4.x branch by tightening parameter type declarations from the generic Node to AbstractExpression in several expression/binary/unary node constructors and in TrueTest::wrap, and by removing a now-redundant array_map in Environment::resolveTemplate. The changes align the enforced runtime types with the existing docblock intent and add a @var annotation in IfNode to satisfy static analysis.

Changes

Layer / File(s)	Summary
type-hint tightening
src/Node/Expression/Binary/AndBinary.php	Narrows constructor params from Node to AbstractExpression, swapping the import accordingly.
src/Node/Expression/Binary/OrBinary.php	Narrows constructor params from Node to AbstractExpression.
src/Node/Expression/Binary/XorBinary.php	Narrows constructor params from Node to AbstractExpression.
src/Node/Expression/Binary/ElvisBinary.php	Replaces Node params (plus redundant docblock) with AbstractExpression type hints.
src/Node/Expression/Unary/NotUnary.php	Narrows the constructor param from Node to AbstractExpression.
src/Node/Expression/Test/TrueTest.php	Changes wrap() signature and return type from Node to AbstractExpression.
src/Node/IfNode.php	Adds an @var AbstractExpression annotation for the test node before passing it to TrueTest::wrap.
dead-code removal
src/Environment.php	Drops the array_map handling of TemplateWrapper in the error message, imploding $names directly.
