git-graffiti tool for changing Git commit hash prefixes

git-graffiti is a Rust-based tool for modifying Git commit hash prefixes.

The program uses a brute-force method to search for a nonce value that produces the desired hash prefix.

Users can create visually appealing or meaningful character sequences in their commit history.

Example target prefixes include "dead000", "beef000", or "c0ffee0".

This allows users to personalize their commit history, making it more readable or amusing when viewed using the git log --oneline command.
