Reject template wrappers from another environment
Twig now rejects `TemplateWrapper` instances created by another `Environment`.
This prevents templates from unexpectedly using another environment's loader, extensions, globals, or sandbox policy.

Remove the documentation comments compilation overhead
Documentation comments are now attached to semantic nodes during parsing, removing the dedicated AST traversal. Token parsers returning placeholder nodes can select the semantic documentation target.

Release destructuring temporaries after assignment
The compiled destructuring code kept the right-hand side alive in a hidden local until the end of rendering, wasting memory on large arrays and iterators. The temporary is now cleared as part of the compiled expression.
The way it works:
For this Twig expression:
```twig
{% do {name, email: address} = user %}
```
The previous generated expression was conceptually:
```php
[$context["name"], $context["address"]] = [
getAttribute($_v0 = $context["user"], "name"),
getAttribute($_v0, "email"),
];
```
The branch now generates:
```php
[
[$context["name"], $context["address"]] = [
getAttribute($_v0 = $context["user"], "name"),
getAttribute($_v0, "email"),
],
$_v0 = null,
][0]
```
The important wrapper is:
```php
[$originalExpression, $_v0 = null][0]
```
PHP evaluates array elements from left to right:
1. The original destructuring assignment runs.
2. The temporary variable is set to `null`, releasing its reference.
3. `[0]` returns the result of the original expression.
This preserves Twig’s rule that a destructuring expression returns its right-hand value.

Deprecate prefixed macro definedness checks
Testing a macro through a legacy `macro_`-prefixed name would have silently returned `false` in Twig 4.0 without ever warning; `has()` now triggers the same deprecation as `call()`.

Fix Stringable keys for ArrayAccess implementations
This restores support for `Stringable` keys on string-keyed `ArrayAccess` implementations such as `ArrayObject` and `ArrayIterator`, while preserving object keys for `SplObjectStorage`.
The object key is attempted first and is converted to a string only when the implementation rejects it. The optimized and strict lookup paths now share the same behavior without duplicate existence checks.
