WillTools: precast shop-ticket QC and panel handling tools

Public demo snapshot of an in-house pyRevit extension for precast concrete
shop-ticket QC (37 checks / 46 checklist rows) and a standalone panel
handling solver (PCI Chapter 8).

- No client, job, plant or product data: knowledge layers ship as
  structural templates only.
- Ticket QC's model-read escalation targets a LAN model server endpoint
  (configurable), not a cloud provider.
- Built from the private development repo via tools/make_dist.py.

+# All three rows are half-built and all three say so in their own titles.
+# Keep the (WIP) suffixes until the tool behind one actually runs: the arrow
+# hides them from the ribbon, but a row that opens is still a row somebody
+# clicks. PanelAnalysis differs from its two siblings in one way worth
+# naming: it DOES run, end to end, and opens a real page -- what is
+# unfinished is the analysis pipeline behind the page it opens, not the
+# button itself. See that button's own script.py.
+#
+# Anything not listed here is not created. Add a button, add it here.
