Title: Move BuildResidentialHPXML measure to option-based arguments
Description: Refactors ResStock to use the new BuildResidentialHPXML measure, which now has ~100 options instead of ~600 detailed properties as arguments. Also moves much of the ResStock special sauce around configuring the HPXML models into the ResStockArgumentsPostHPXML measure. The options_lookup.tsv file is now significantly simpler.

Title: Add baseline_validation tool to resstockpostproc
Description: Adds a baseline validation tool that compares a ResStock baseline run against public data sources (EIA 861, EIA 176, RECS 2020, LRD) and generates an interactive comparison dashboard. Supports annual and monthly resolutions across U.S. Total, state, census division, building type, vintage, climate zone, and heating-fuel aggregations. A baseline-validation CI job runs the tool under –test on every PR and uploads the generated dashboard as a CI artifact for review.
