System Performance Remediation

Core Principle: First, do no harm. Kill OBVIOUSLY useless processes before touching anything potentially useful.

The Whack-a-Mole Anti-Pattern: Killing child processes (cargo builds, tests) is POINTLESS if confused parent agents respawn them. Kill the confused agents, not their children.

uptime && nproc && cat /proc/pressure/cpu | head -1

# === ONE-LINER STATUS (includes swap + memory pressure) ===
