Adds three coordinated changes:
- Request nameplate, summer, and winter capacity from the EIA
operating-generator-capacity endpoint and project them as typed columns
on energy_eia_operating_generator_capacity_flat. The original ingest
only pulled latitude and longitude, leaving the flat table with no MW
values despite its name.
- New cluster_analysis.ipynb joins master_data_centers to ACS-2024
demographics, USDA RUCA-2020 codes (loaded from new/), and EIA
generation capacity within 50 km of each site.
- Summary doc consolidates the headline findings: DC tracts skew higher
income / more educated / more racially diverse than US average, the
metro over-index is only 1.11x, the non-metro tail is dominated by
hyperscalers in the Columbia River corridor (OR+WA = 66% of non-metro
DCs), and Microsoft co-locates with Palo Verde Nuclear in Goodyear AZ.
