Increment Mode should also update local git commit hash

Hi, The previous feature of incrementing and simultaneously updating the commit hash from local git commit should be bought back, because version:commit is just adding one number to the commit and is confusing, whereas we tend to forget tagging after each commit

Start by tracing the version:commit implementation and the code that reads the local Git commit hash. Review the project's earlier implementation of incrementing with the local hash, then verify that increment mode produces the intended hash-based version without requiring a separate tag.
