docs: improve documentation and clarity across multiple files

- Update flag descriptions for better clarity in `commit.go`
- Expand the `Long` description in `completion.go` to include detailed instructions for loading shell completions
- Improve comments and error messages in `config.go` and `hepler.go` for better readability and clarity
