WillTools 2026-09-09 -- clean snapshot of the development repo for review

History-free snapshot of the private development repository at 77a82eb.
Code, docs and the public catalogue only: no plant or job knowledge
layers, no client, job or producer names (tools/scrub.py clean against
the widened term list; a second word-level grep clean). The intro deck is
left out because its slide images cannot be checked for job drawings.

+# WillTools host-side (CPython) dependencies -- tools/*.py and both pytest
+# suites. NOT the Revit extension: that runs under pyRevit's own IronPython
+# and never imports from a site-packages directory.

+# Written 2026-09-01 because nothing in this repo named these before that,
+# and a script should not be the only place a dependency list lives (see
+# tools/setup_machine.py, which installs from this file). Install with:
