[Feature]: generate quantity - Generates the number of commit messages to choose from

[TunaKHH]

Description

Hello,
In my usage scenario, the content generated by AI is often not what I want to use, and it usually takes multiple attempts to get what I want to use.
I hope to generate multiple commit titles for me to choose from. For the simplicity of the screen, I think oco can not generate a commit body when starting this function.

Suggested Solution

Current：Confirm the commit message?

chore(tests.mak): add Makefile targets for building

- Introduced Makefile targets for building and cleaning project files
- Simplified the build workflow, reducing setup time for development
- Adjusted dependencies to ensure compatibility with the new targets
 

When the setting is completed： oco config set generate=5
Expect：Pick a commit message to use

chore(docs): update README with new installation steps
chore(scripts): add Makefile targets for testing
chore(build): optimize Dockerfile for faster builds
chore(deps): upgrade dependencies for improved security
chore(ci): add new workflow for automated testing
