👀 Proposal: Integrate SwiftGitX as an Alternative to the Current Git Implementation

I would like to propose integrating [SwiftGitX](https://github.com/ibrahimcetin/SwiftGitX) into CodeEdit as an alternative to the current `GitClient` implementation that relies on executing Git shell commands.

## Background

Currently, CodeEdit uses a `GitClient` class that wraps Git shell commands by spawning subprocesses, capturing output, and then parsing the results to build models. While this approach works, it has some limitations:

- Performance Overhead: Each Git operation requires spawning a new process, which can be slow compared to directly interacting with Git data structures.

- Error Handling: Parsing command-line output can be fragile and error-prone, as Git’s output format may change between versions.

- Dependency on Git Executable: The current approach requires the Git binary to be installed and available in the system’s PATH.

## About SwiftGitX

SwiftGitX is a Swift-native wrapper around libgit2, providing a structured and efficient way to interact with Git repositories programmatically. Key advantages include:

- Direct Interaction with Git Repositories: No need for shell commands; everything is handled in Swift.

- Better Performance: By avoiding process spawning and output parsing, operations are faster and more efficient.

- **No External Dependencies**: SwiftGitX does not require an external Git installation; it can be added as a Swift package and works out of the box.

- **Well-Tested**: The library includes more than 100 unit tests and 90% test-coverage, ensuring reliability and stability.

## Proposed Plan for Incremental Integration

To avoid a large and disruptive refactor, I propose an incremental approach:

1. Introduce SwiftGitX as an optional dependency – Add SwiftGitX to the project while keeping the existing GitClient implementation.

2. Implement Core Functionality – Start by replacing a small subset of Git operations (e.g., getting repository status, listing branches) to validate the integration.

3. Expand Coverage – Gradually replace more Git operations with SwiftGitX where it provides clear advantages.

4. Evaluate and Optimize – Compare performance, reliability, and maintainability before considering a full migration.

## Next Steps

I’d love to discuss this proposal with the maintainers and contributors of CodeEdit. If this approach sounds reasonable, I can start working on the initial integration and provide PRs step by step.

Looking forward to your feedback!

Empieza leyendo la implementación existente de GitClient y la configuración de dependencias del proyecto para comprender la integración actual de shell-command. La propuesta no identifica archivos ni pruebas específicos; para darlo por terminado se necesitaría acordar una integración incremental de SwiftGitX, operaciones iniciales como consultar el estado del repositorio o listar ramas, y cobertura de evaluación.
