feat!: allow mapping to any type Previously, the method `TreeMapper::map` would allow mapping only to an object. It is now possible to map to any type handled by the library. It is for instance possible to map to an array of objects: ```php $objects = (new \CuyZ\Valinor\MapperBuilder())->mapper()->map( 'array<' . SomeClass::class . '>', [/* … */] ); ``` For simple use-cases, an array shape can be used: ```php $array = (new \CuyZ\Valinor\MapperBuilder())->mapper()->map( 'array{foo: string, bar: int}', [/* … */] ); echo strtolower($array['foo']); echo $array['bar'] * 2; ``` This new feature changes the possible behaviour of the mapper, meaning static analysis tools need help to understand the types correctly. An extension for PHPStan and a plugin for Psalm are now provided and can be included in a project to automatically increase the type coverage.

feat!: add access to root node when error occurs during mapping When an error occurs during mapping, the root instance of `Node` can now be accessed from the exception. This recursive object allows retrieving all needed information through the whole mapping tree: path, values, types and messages, including the issues that caused the exception. It can be used like the following: ```php try { (new \CuyZ\Valinor\MapperBuilder()) ->mapper() ->map(SomeClass::class, [/* ... */]); } catch (\CuyZ\Valinor\Mapper\MappingError $error) { // Do something with `$error->node()` // See README for more information } ``` This change removes the method `MappingError::describe()` which provided a flattened view of messages of all the errors that were encountered during the mapping. The same behaviour can still be retrieved, see the example below: ```php use CuyZ\Valinor\Mapper\Tree\Message\Message; use CuyZ\Valinor\Mapper\Tree\Node; /** * @implements \IteratorAggregate<string, array<\Throwable&Message>> */ final class MappingErrorList implements \IteratorAggregate { private Node $node; public function __construct(Node $node) { $this->node = $node; } /** * @return \Traversable<string, array<\Throwable&Message>> */ public function getIterator(): \Traversable { yield from $this->errors($this->node); } /** * @return \Traversable<string, array<\Throwable&Message>> */ private function errors(Node $node): \Traversable { $errors = array_filter( $node->messages(), static fn (Message $m) => $m instanceof \Throwable ); if (! empty($errors)) { yield $node->path() => array_values($errors); } foreach ($node->children() as $child) { yield from $this->errors($child); } } } try { (new \CuyZ\Valinor\MapperBuilder()) ->mapper() ->map(SomeClass::class, [/* ... */]); } catch (\CuyZ\Valinor\Mapper\MappingError $error) { $errors = iterator_to_array(new MappingErrorList($error->node())); } ``` The class `CannotMapObject` is deleted, as it does not provide any value; this means that `MappingError` which was previously an interface becomes a class.
