feat(routines): inventory pinned G36 source trees

[jscott3201]

Summary

• inventory every regular Git blob below the G36 source root at the pinned release and development revisions
• retain and verify the shared Modelica Buildings legal notice byte-for-byte
• add deterministic generation/checking, hostile fixture tests, and exact-pin CI checkouts

Scope

This is the L1 source-evidence boundary. It keeps the canonical and generated registries empty, coverage planned, and routine execution disabled. Release and development snapshots remain separate.

package.order is inventoried as ordinary source bytes. This PR does not interpret its members or claim Modelica declarations, classes, dependency closure, source-family mapping, specialization, generated CXF, or executable coverage.

Source evidence

• release 55abf579598ca81cae0a82f337350375958e6722: 431 files, tree 8bc765b009ed0dcf6907021f073ea77160088bd8
• development eccb40b3974bb10eef120c5670a6454e43ca36e3: 693 files, tree 6286a3d534846a187444d3b4bee72a1ae944a458
• shared legal blob b542af56c10d3769d42a79ad45d78329ad2dbd5f

Validation
