Module metrics 

Metrics and observability for production monitoring

This module provides comprehensive metrics tracking for IPFRS operations, enabling production monitoring, performance analysis, and capacity planning.

Features

• Operation Counters - Track blocks created, CIDs generated, bytes processed
• Performance Metrics - Latency percentiles, throughput rates
• Resource Usage - Memory allocations, pool hit rates
• Error Tracking - Error counts by type and category
• Health Checks - System health and readiness indicators

Example

use ipfrs_core::metrics::{global_metrics, MetricsSnapshot};

// Record operations
let metrics = global_metrics();
metrics.record_block_created(1024);
metrics.record_cid_generated(50); // microseconds

// Get snapshot for monitoring
let snapshot = metrics.snapshot();
println!("Blocks created: {}", snapshot.blocks_created);
println!("Total bytes: {}", snapshot.total_bytes_processed);
println!("Avg CID generation: {:.2}µs", snapshot.avg_cid_generation_us);
