Closes: #1176

What changed? Why?

Removes the unbalanced summary-to-detail Make/Use FBS methods (Detail_Use_SUT, Detail_Use, Detail_Make). The nowcast path never used them: Supply seeds from Detail_Supply_Mix_*, and Use is Balanced_Detail_Use_SUT. Their only live nests were CAP_HAP 2014 and 2020, which this change retires (sector methods plus national/state wrappers). CAP_HAP 2017 stays on BEA_Detail_Use_SUT. Drops catalog-only orphans BEA_Summary_Use_PRO_BeforeRedef and BEA_Summary_Make_BeforeRedef; keeps BEA_Summary_Use_SUT beside BEA_Summary_Supply. Updates analysis/nowcasting/plan.md so Use-side fallback language no longer points at Detail_Use_SUT.

Any later CAP_HAP 2014/2020 (or other year) rebuild should attribute from nowcast balanced Use (Balanced_Detail_Use_SUT or an equivalent nowcast-derived product), not from these retired summary-to-detail FBS methods.

Impact

No USA / nowcast / MUT / EF output change; those paths never called the deleted methods.

Testing

rg confirms no remaining !include of Detail_Use_SUT.yaml, Detail_Use.yaml, or Detail_Make.yaml, and CAP_HAP 2014/2020 wrappers are gone.

rg "Detail_Use_SUT\.yaml|Detail_Use\.yaml|Detail_Make\.yaml|CAP_HAP_.*_(2014|2020)" bedrock --glob "*.{yaml,yml,py,md}"
