dedup-go is a simple, fast, idiomatic Go tool to detect and remove duplicate files in a directory by computing their content hashes.
It’s designed to be a lightweight, real-world example of writing robust Go CLIs and learning file I/O, hashing, and concurrency.

• Scan any target directory recursively
• Compute SHA-256 hashes for file comparison
• Report duplicates and optionally delete them
• Clean, modular Go project structure
• Ready for use as a CLI or as a library

# Clone the repo
