Merge feature/fix-csharp-and-config-type-bugs: C3.10 Signal Flow + Complete Godot Support

Features:
- C3.10: Signal Flow Analysis for Godot projects (208 signals, 634 connections)
- Complete Godot game engine support (.gd, .tscn, .tres, .gdshader)
- GDScript dependency extraction with preload/load/extends patterns
- GDScript test extraction (GUT, gdUnit4, WAT frameworks)
- Signal-based how-to guides generation

Fixes:
- GDScript dependency extraction (265+ syntax errors eliminated)
- Framework detection false positive (Unity → Godot)
- Circular dependency detection (self-loops filtered)
- GDScript test discovery (32 test files found)
- Config extractor array handling (JSON/YAML root arrays)
- Progress indicators for small batches

Tests:
- Added comprehensive GDScript test extraction test case
- 396 test cases extracted from 20 GUT test files
