Description:
Create a pixel connectivity layer for each activity to measure how strongly each pixel is spatially connected to others within the activity. Clustered pixels should score higher than isolated ones. The resulting layer will be used alongside constant rasters in investability analysis.

Acceptance Criteria:

• Compute connectivity scores per pixel.
• Clustered pixels have higher scores than isolated pixels.
• Scores normalized to 0–1 range.
• Output raster integrates with the investability workflow.
