Subject: [PATCH 01/11] Add cross-file component import edges

This PR implements cross-file edges that represent imports between files, specifically tracking when components from one file are imported in another.

Features added:
- Enhanced import resolution to detect specific components being imported between files
- Added a new relationship type "imports_component" to distinguish component imports
- Implemented support for various import styles (regular, aliased, parenthesized, star imports)
- Added comprehensive tests to verify the functionality

These relationships can be colored differently on the frontend to distinguish them from other edge types. The implementation is Python-specific as requested but designed to be extensible for other languages in the future.

Closes # 22

Subject: [PATCH 03/11] Fix type checking error in test

Fixed an error in the test_component_import_extraction test where
analyzer.data was initialized with an incomplete dictionary structure
that didn't match the expected RepositoryData type.

By properly initializing with a complete schema structure including all
required fields (metadata, files, relationships, history, customData),
the type checking issue is resolved.

Fixed the type checking error by using the proper create_empty_schema()
function to initialize the analyzer.data with the correct RepositoryData
type. This ensures the data structure has the right type annotation.

- Added the import at the module level
- Used the proper schema initialization function
- Cleaned up comments for clarity

Subject: [PATCH 05/11] Refactor to use astroid and improve frontend
 visualization

This commit makes several improvements based on feedback:

1. Backend changes:
   - Replaced regex-based Python import detection with robust astroid AST parsing
   - Improved component import detection using proper static analysis
   - Refactored code to be more maintainable and extensible

2. Frontend changes:
   - Added distinct colors for different relationship types
   - Made component imports purple to distinguish them from file imports (blue)
   - Added a relationship types section to the visualization legend
   - Improved overall visualization with better link styling

These changes make the visualization more useful by clearly showing the
different types of relationships with appropriate colors.

Subject: [PATCH 06/11] Fix linting issues in analyzer.py

Fixed three linting issues found by the CI check:
- Renamed unused alias variables to _alias (B007)
- Used Optional type annotation explicitly for component_names parameter (RUF013)

Subject: [PATCH 07/11] Fix CI issues with missing dependency and test
 compatibility

- Added astroid to project dependencies in pyproject.toml
- Added a compatibility method _extract_component_imports to
  support existing tests without reverting our astroid implementation
- The compatibility method uses the same interface as the old method
  but delegates to the new implementation internally
