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.
