fix: Add GDScript-specific dependency extraction to eliminate syntax errors

PROBLEM:
- 265+ "Syntax error in *.gd" warnings during analysis
- GDScript files were routed to Python AST parser (_extract_python_imports)
- Python AST failed because GDScript syntax differs (extends, signal, @export)

SOLUTION:
- Created dedicated _extract_gdscript_imports() method using regex
- Parses GDScript-specific patterns:
  * const/var = preload("res://path")
  * const/var = load("res://path")
  * extends "res://path/to/base.gd"
  * extends MyBaseClass (with built-in Godot class filtering)
- Converts res:// paths to relative paths
- Routes GDScript files to new extractor instead of Python AST

CHANGES:
- dependency_analyzer.py (line 114-116): Route GDScript to new extractor
- dependency_analyzer.py (line 201-318): Add _extract_gdscript_imports()
- Updated module docstring: 9 → 10 languages + Godot ecosystem
- Updated analyze_file() docstring with GDScript support

IMPACT:
- Eliminates all 265+ syntax error warnings
- Correctly extracts GDScript dependencies (preload/load/extends)
- Completes C3.10 Signal Flow Analysis integration
