//! Dirty account tracking and snapshot/restore for fast fuzzing iterations.
//!
//! Instead of cloning the entire LiteSVM state each iteration (O(all_accounts)),
//! this module tracks which accounts were modified and restores only those
//! (O(dirty_accounts), typically ~5-20 vs ~50-200+ total).
//!
//! # Architecture
//!
//! - **DirtyTracker** — accumulates writable accounts across all transactions in an iteration
//! - **SvmSnapshot** — captures account state at setup time, restores only dirty accounts
//! - **AccountDiff** — before/after diffs for account state comparison
