The answer: ~/.local/bin

✅ XDG standard compliant
✅ One-line PATH setup
✅ Git-versioned if you want
✅ Zero ceremony, 100% reversible

🔒 Quick tip for users:

Use `minimumReleaseAge` for stability, but need an emergency security update?

`minimumReleaseAgeExclude` lets you bypass the wait for specific packages without disabling your safety net.
