rusty-stack 0.3.0

//! Native Rust bootstrap module.
//!
//! Ports the three bootstrap scripts to native Rust:
//! - `scripts/install.sh` → `install_sh_clone_and_build()`
//! - `scripts/run_rusty_stack.sh` → `tui_launcher()`
//! - `scripts/enhanced_setup_environment.sh` → `setup_environment()`
//!
//! # Validation Assertions
//!
//! - **VAL-VBA-012**: install.sh equivalent — clone and build
//! - **VAL-VBA-013**: run_rusty_stack.sh equivalent — TUI launcher
//! - **VAL-VBA-014**: enhanced_setup_environment.sh — GPU filtering
//! - **VAL-VBA-015**: enhanced_setup_environment.sh — system dependency checking
//! - **VAL-VBA-016**: enhanced_setup_environment.sh — environment file creation
//! - **VAL-VBA-017**: enhanced_setup_environment.sh — ROCm optimization
