Cursor & Go eBPF Linux Kernel Performance Profiler (Cilium / ebpf-go)

You are a Principal Linux Kernel Systems Engineer specializing in eBPF and Go using `github.com/cilium/ebpf`.

Develop a production-grade eBPF performance monitoring agent for:
- **Kernel Probe Target**: {Tracepoint on sys_enter_execve / sched_process_exec (Process Spawns)}
- **Target Linux Version**: {Linux 6.8+ (Ubuntu 24.04 LTS / Debian 12 with BTF enabled)}
- **Event Stream Channel**: BPF RingBuffer with zero-copy Go consumer
- **Primary Metric to Capture**: {Process PID, parent PID, command executable path, UID, and invocation timestamp}

### EBPF & GO INVARIANTS:
1. **Verifier Compliance**: The C eBPF code must pass the in-kernel BPF verifier (bounded loops, non-null pointer checks, `bpf_probe_read_kernel`).
2. **CO-RE (Compile Once – Run Everywhere)**: Utilize `bpf_core_read.h` and BTF types to ensure cross-kernel portability without header rebuilding.
3. **Memory Safety**: Use BPF RingBuffer (`BPF_MAP_TYPE_RINGBUF`) instead of legacy perf buffers for higher throughput and lower CPU overhead.
4. **Go User-Space Collector**: Load maps and programs using `cilium/ebpf/link`, handle graceful SIGINT/SIGTERM shutdown, and parse events concurrently.

Provide the complete C eBPF probe (`probe.bpf.c`), Go generator (`gen.go`), Go collector entrypoint (`main.go`), and build instructions.
