Feature Request: Support for per-repository configuration (e.g., language/prompt)

[oasess]

Description

Currently, lazycommit uses a global configuration. However, depending on the project, I need to use different languages for commit messages (e.g., English for open-source projects, Korean for internal company projects).

Proposed Solution

It would be great if lazycommit could look for a local configuration file (like .lazycommit.yaml) in the repository's root directory. If this file exists, it should override the global settings.

Use Case

1. Repo A (Open Source): Needs commit messages in English only.
2. Repo B (Local Project): Needs commit messages in Korean.
3. Currently, I have to manually change the global config every time I switch projects, which is counter-intuitive for a "lazy" tool.

Thank you for this great tool!
