Crate symbiotic 

Performance profiling for Polars benchmarks

This crate collects process-specific performance metrics:

• Process CPU time and usage
• Process memory (RSS, virtual, heap, stack)
• Page faults and allocator statistics
• Thread pool metrics
• Hardware performance counters (optional)
