test: Add comprehensive validation tests for improved brace validation
- Add ManageScriptValidationTests.cs: Unity-based validation tests for structural balance checking - Add test_improved_anchor_matching.py: Python tests for enhanced anchor pattern matching - Remove obsolete test_regex_delete_guard.py (functionality moved to C# validation) - Tests validate the scoped validation fixes and anchor matching improvements 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>main
