spydecy-debugger 0.1.0

//! Spydecy Interactive Debugger
//!
//! This module implements the introspective debugger that allows stepping through
//! the transpilation process to identify issues. Built incrementally alongside
//! the transpiler (per Gemini's recommendation).
//!
//! # Sprint 2 Feature
//!
//! `visualize python-ast` - Display Python AST and HIR conversion
