prune: sweep Science to the shortlist cap

Per ADR-0001, maintainer-adjudicated at the Data & Science preview
review (2026-08-15, all rows live-verified). Restructure first: Core
narrows to numba, numpy, scipy; mint Symbolic Mathematics (sympy),
Statistics (statsmodels), Graphs and Networks (networkx), and
Computational Geometry (shapely) — five co-obvious tools doing five
different jobs, the decision-13 pattern. Other shrinks to a two-entry
grab-bag; colour renamed to colour-science per the PyPI-name convention
(bare 'colour' on PyPI is an unrelated color-conversion library). Then
cap.

Removed (downloads are PyPI last-30-days via BigQuery, 2026-08-15):

- cclib (29.7K/month): computational-chemistry log parsing, small
  audience
- openbabel (54.9K/month pip; conda-forge adds only 1.8M all-time):
  legacy toolbox next to rdkit
- pydy (1.2K/month): near-zero usage
- PythonRobotics: educational algorithm compilation ("sample codes and
  textbook" per its own description), not a library; not on PyPI
- pathsim (6.3K/month): no adoption
