Track disk usage, memory consumption (current + peak), and I/O throughput during indexing runs. Progress tracking hooks into brk_logger to record processing milestones automatically.

Key Features

Multi-metric monitoring: Disk, memory (RSS + peak), I/O read/write
Progress tracking: Integrates with logging to capture block heights as they're processed
Run comparison: Outputs timestamped CSVs for comparing multiple runs
macOS optimized: Uses libproc for accurate process metrics on macOS
Non-blocking: Monitors in background thread with 5-second sample interval

Core API

let mut bencher = Bencher::from_cargo_env("brk_indexer", &data_path)?;
bencher.start()?;

// ... run indexing ...

bencher.stop()?;
