[esalama01]

Hi team,

Adding my Go implementation for the "Build Your Own Git" challenge.

Implementation Details:

• Language: Go 1.21
• Features Completed: init, hash-object, add (index management), status, commit (Merkle tree traversal), and diff (Myers algorithm).
• Architecture: Built a custom content-addressable storage (CAS) handling blob, tree, and commit objects with zlib compression and SHA-1 hashing.

Thanks!
