feat(sdk): add cgr shim package for short Python imports

[vitali87]

Summary

• Add cgr/ shim package that re-exports SDK components from codebase_rag
• Register cgr in [tool.setuptools] packages

Users who pip install code-graph-rag can now use short imports:

from cgr import load_graph, GraphLoader, MemgraphIngestor, CypherGenerator, embed_code, settings

Instead of the longer form:

from codebase_rag.graph_loader import load_graph
from codebase_rag.services.graph_service import MemgraphIngestor
from codebase_rag.services.llm import CypherGenerator

Both import styles continue to work. The cgr CLI command is unaffected.

Summary of Changes

Hello @vitali87, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the developer experience for the code-graph-rag SDK by simplifying import statements. It achieves this by creating a new cgr shim package that re-exports key functionalities, making the SDK more convenient and concise to use without affecting existing import styles or the cgr CLI command.

Highlights

• Shorter Python Imports: Introduced a new cgr shim package that re-exports core SDK components from codebase_rag, enabling users to import functionalities like load_graph, GraphLoader, and MemgraphIngestor directly from cgr.
• Package Registration: Registered the newly created cgr package within the pyproject.toml file under [tool.setuptools] packages to ensure it is properly included during installation.

Changelog

• cgr/init.py
  • Added a new shim package to re-export core SDK components.
• pyproject.toml
  • Registered the new cgr package with setuptools.
• uv.lock
  • Updated the code-graph-rag package version.

Greptile Summary

Adds a convenience shim package cgr/ that provides shorter import paths for the SDK's main components. Users can now use from cgr import load_graph, GraphLoader instead of from codebase_rag.graph_loader import load_graph, GraphLoader. Both import styles remain supported.

The implementation:

• Creates a new cgr/__init__.py with re-exports from codebase_rag
• Registers the cgr package in pyproject.toml for setuptools discovery
• Updates version to 0.0.78 in the lock file

The change is backwards compatible and follows the same pattern as the existing codec package. All re-exported symbols (settings, embed_code, GraphLoader, load_graph, MemgraphIngestor, CypherGenerator) exist in the codebase and are properly imported.

Confidence Score: 5/5

• Safe to merge with no issues
• This is a straightforward, low-risk convenience feature that adds a shim package for shorter imports. All re-exported components exist and are correctly imported. The change is purely additive (no modifications to existing code), backwards compatible, and follows established patterns in the codebase (similar to the codec package). The package is properly registered in pyproject.toml for setuptools discovery.
• No files require special attention

Important Files Changed

pyproject.toml	Added cgr to setuptools packages list for package discovery
uv.lock	Version bump from 0.0.76 to 0.0.78 in lock file

Code Review

This pull request introduces a cgr shim package to allow for shorter, more convenient imports of the SDK's main components. The changes include adding the cgr/__init__.py file to re-export the components and updating pyproject.toml to include this new package. The implementation is straightforward and effective. I've added one minor suggestion to improve code style by sorting the __all__ list alphabetically.
