GIS/DEM preprocessing for SWMM experiments using the user's own QGIS/GRASS layers. Use when Zhonghao asks to (1) delineate subcatchments through QGIS/GRASS (standard or entropy-guided), (2) preprocess QGIS-derived subcatchment polygons into builder-ready CSV, (3) identify high-entropy hotspot subcatchments, or (4) expose QGIS/GRASS-backed preprocessing as MCP tools for reproducible workflows.

SWMM GIS / Preprocess
Before calling any watershed delineation tool — ask the user
When Zhonghao triggers watershed delineation (qgis_raw_to_entropy_partition or equivalent), always ask these questions first before making the tool call:
Delineation mode — Standard (fast, direct GRASS basins, no entropy) or Entropy-guided (paper WJE/NWJE/WFJS split-lump with sensitivity figures)?
Stream threshold — How many upslope cells define a stream? Default 100. Smaller = more str
