feat: add GitExtractor component

[raphaelchristi]

This pull request introduces a new component called GitExtractorComponent to the langflow project, for analyzing Git repositories.

Features:

• Repository Info: Extracts branch, remotes, and commit details
• Statistics: Calculates file counts, sizes, and line numbers
• Directory Structure: Generates complete folder tree
• File Content: Extracts text files with binary handling
• Memory Safe: Implements content truncation for large repos
• Error Handling: Graceful error recovery and resource cleanup

The GitExtractorComponent is designed to analyze a Git repository and provide various information and file contents. Additionally, the __init__.py file has been updated to include this new component.

New component addition:

• src/backend/base/langflow/components/git/gitextractor.py: Introduced the GitExtractorComponent class, which includes methods for retrieving repository information, statistics, directory structure, file contents, and text-based file contents. This component uses asynchronous context management for temporary Git repository cloning and handles potential GitError exceptions.

Initialization update:

• src/backend/base/langflow/components/git/__init__.py: Added GitExtractorComponent to the module's exports, ensuring it is available for use in other parts of the application.

Hey, @raphaelchristi

This is looking good.

The tmpdir calls are blocking and it would be better if they were async. Could you refactor that?

Also, you don't need to delete the folder because you could use a context manager that will remove the folder once the code block runs.

Hi @ogabrielluiz ,

Thank you for the review! I've implemented the suggested changes:

• Converted all methods to async using async/await
• Added asynccontextmanager for the tmpdir operations
• Implemented automatic cleanup using the context manager

Let me know if you'd like me to make any additional adjustments to the implementation.
