Module checkpoint 

Pipeline checkpoint system for resume functionality.

This module provides checkpoint management for Ralph’s pipeline:

• Save and load pipeline state
• Resume interrupted pipelines
• Track pipeline phase progress

Example

use ralph::checkpoint::{PipelineCheckpoint, PipelinePhase, save_checkpoint, load_checkpoint};

// Save a checkpoint
let checkpoint = PipelineCheckpoint::new(
    PipelinePhase::Development,
    2,  // current iteration
    5,  // total iterations
    0,  // reviewer pass
    2,  // total reviewer passes
    "claude",
    "codex",
);
save_checkpoint(&checkpoint)?;

// Load and resume
if let Some(checkpoint) = load_checkpoint()? {
    println!("Resuming from: {}", checkpoint.description());
}
