Modified from original source (https://gist.github.com/krzyzanowskim/a7faf277cd0b88cbff23bd9b52a4bd2a), in order to add ability to (optionally) pass in a semantic commit (e.g., git commit-ai fix), use a preferred local LLM (llama3.1 via ollama), and the ability to preview or regenerate a commit message.
