mini.diff Integration and Per-Change Review for @mcp Tool in CodeCompanion

[meijieru]

Currently, the @mcp tool within CodeCompanion defaults to displaying diffs in a split view. Given that CodeCompanion supports the mini.diff backend, could the @mcp tool be configured to utilize mini.diff? This could offer users alternative diff presentations, such as a non-split view.

Additionally, we would like to request the implementation of functionality that allows for accepting or rejecting individual changes directly within the diff interface, providing more granular control over a_changes.

Thanks!

@meijieru Thank you. I agree that the current write_file and replace_in_file can be much better. I created the native neovim server to demonstrate how users can create their own MCP servers in lua. Much focus is not put into the fine details of it. But having a almost perfect dev tools server implementation is something in the roadmap. Regarding the mini diff we can check if mini diff plugin is available and use it to show diff falling back to the current one.

Will update it soon. You are welcome to open a PR 😅
