• PR: feat: add nesting depth to complexity metrics (#150)

• Description: Add maximum nesting depth calculation to complexity analysis. Store function AST node in the CFG to enable calculating CFG-based (cyclomatic complexity) and AST-based (nesting depth) metrics in a single pass.

• Changes Made:

  • Add NestingDepth field to domain.ComplexityMetrics
  • Add FunctionNode field to analyzer.CFG
  • Calculate nesting depth in CalculateComplexityWithConfig
  • Include nesting_depth in JSON, YAML, and CSV outputs
  • Update tests for new CSV column

• PR: feat: Add maximum nesting depth calculator for Python functions (#143)

• Description: Implements a function to calculate the maximum nesting depth for Python functions by traversing their Abstract Syntax Tree (AST).

• Changes Made:

  • New file: internal/analyzer/nesting_depth.go
    • CalculateMaxNestingDepth(): Computes max nesting depth for a single Python function
    • traverseForNesting(): Recursive AST traversal helper
    • isNestingNode(): Determines node types that increase nesting depth
    • isComprehensionNode(): Identifies comprehension nodes
    • NestingDepthResult: Holds nesting depth metrics and location info
  • New file: internal/analyzer/nesting_depth_test.go
    • Comprehensive test coverage with 10+ test cases
    • Scenarios: if, for, while, try, with, comprehensions, lambdas
    • Edge cases: nil nodes, simple functions, complex nesting (depth 4+)
