  Description     : BPF-based tool that tracks kernel metrics related to scheduling

A BPF-based tool written in Rust that tracks kernel metrics related to
scheduling. The goal is to give a high level overview of kernel
process scheduling decisions with relatively low overhead.

rsched uses tracepoints and performance counters to monitor:
- Scheduling delays: Time spent waiting in the runqueue
- Time slice analysis: Duration and preemption statistics
- Runqueue depth: Number of tasks waiting when processes are woken
- Wakeup delays: Time from sched_waking to sched_switch
- schedstats: via /proc/schedstats
- CPU cycles and instructions: both user and kernel time
