# Python egg-info and Editable Install Support

## Module
Scanner

## Status
IMPLEMENTED

## Description
Extends Python analyzer to discover packages installed via legacy egg-info metadata format and pip editable installs (pip install -e), which lack standard dist-info directories.

## Implementation Details
- **Egg-Info Adapter**:
  - `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python/Internal/Packaging/Adapters/EggInfoAdapter.cs` - `EggInfoAdapter` discovers packages installed via legacy egg-info metadata format, extracting package name, version, and dependencies
- **Editable Install Adapter**:
  - `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python/Internal/Packaging/Adapters/PipEditableAdapter.cs` - `PipEditableAdapter` discovers packages installed via `pip install -e` editable installs, which use .egg-link files instead of standard dist-info
- **Package Discovery**:
  - `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python/Internal/Packaging/PythonPackageDiscovery.cs` - `PythonPackageDiscovery` orchestrates discovery across dist-info, egg-info, and editable install paths
  - `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python/Internal/Packaging/PythonPackageInfo.cs` - `PythonPackageInfo` unified package metadata model
  - `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python/Internal/Packaging/PythonPackageKind.cs` - Enum distinguishing dist-info, egg-info, and editable package types
- **Language Analyzer**: `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python/PythonLanguageAnalyzer.cs`

## E2E Test Plan
- [ ] Scan a container with Python packages installed via legacy `python setup.py install` (egg-info) and verify they are discovered
- [ ] Scan a container with pip editable installs (`pip install -e .`) and verify the editable packages are discovered
- [ ] Verify egg-info packages include correct name, version, and dependency metadata in the SBOM
- [ ] Verify editable installs using .egg-link files are correctly resolved to their source paths
- [ ] Verify the package kind (dist-info vs egg-info vs editable) is correctly classified for each discovered package
