Add semantic highlighting for type names after 'Новый' keyword

[Copilot]

Type names following the Новый/New keyword were not receiving semantic token highlighting. This adds type highlighting for constructor expressions.

Changes

• Add NewExpressionSemanticTokensSupplier that finds newExpression AST nodes and emits SemanticTokenTypes.Type for the type name
• Add unit tests covering Russian/English syntax and edge cases

Example

Массив = Новый Массив();        // "Массив" now highlighted as Type
Список = Новый СписокЗначений(); // "СписокЗначений" now highlighted as Type

Note: The Новый("TypeName") syntax where the type is passed as a string literal is intentionally not highlighted, as that's a string argument rather than a type identifier.

Original prompt

Раскраска имен типов после ключевого слова "Новый" как type

Pull request overview

This PR adds semantic highlighting for type names following the Новый/New keyword in constructor expressions and introduces a reusable test helper to improve test maintainability across semantic token tests.

• Implements NewExpressionSemanticTokensSupplier to highlight type names in Новый ТипИмя() expressions as SemanticTokenTypes.Type
• Introduces SemanticTokensTestHelper with utilities for decoding and asserting semantic tokens in tests
• Refactors existing semantic token tests to use the new helper, improving consistency and reducing boilerplate
