Introduce stage option and git staging helper

## CLI Arguments
- Introduced stage flag to stage all changes before generating commit messages.
- Introduced -w shorthand for --apply to write the commit editmsg.
- Introduced -m shorthand for --model to specify the model quickly.
- Introduced -k shorthand for OPENAI_API_KEY for the API key.

## Git
- Introduced stage_all helper to stage all new, modified, and deleted files (git add -A).

## Main
- Wired new stage flag into startup sequence: if cli.stage { stage_all()?; } and imported stage_all for use before LLM client setup.
