Tool suggestion: Cloud Waste Scanner for cloud cost optimization

[ken-water]

Hi maintainers,

Thanks for maintaining this awesome list.
I'd like to suggest adding Cloud Waste Scanner: https://cloud-waste-scanner.com

Why it may fit:

• Focused on identifying cloud waste and unnecessary spend.
• Helpful for teams starting FinOps and cloud cost optimization.
• Practical for DevOps/platform teams that need quick optimization wins.

If this aligns with the list scope, I can open a concise PR entry in the right section.
