Add opt-in checkpoint support gated behind HELION_AUTOTUNE_CHECKPOINT_DIR. When set, the autotuner saves in-progress state each generation and can resume from a checkpoint on subsequent runs. The checkpoint file is deleted on successful completion. Includes pickle serialization support for BaseSearch and PopulationMember, stable-hash-based checkpoint file naming, atomic writes, and kernel recompilation on checkpoint load. stack-info: PR: #1947, branch: yf225/stack/96
