[codex] Implement open CDE and Speckle runtime contract

[ActiveInAI]

Summary

• Adds a runtime Open CDE capability matrix covering ISO 19650 states, buildingSMART/openBIM standards, Speckle object-graph sync, and enterprise adapter boundaries for Glodon, PKPM/Gouli, Autodesk, and Tekla/Trimble.
• Extends openBIM/runtime capability contracts to include IDM, MVD, buildingSMART Validate, and OpenCDE API references.
• Publishes the broader backend, worker, frontend, infrastructure, and standards baseline needed for the CDE/openBIM/Speckle delivery path.
• Removes blocked Rust parser dependency chains (bimifc-parser/eulumdat, ifc-lite/fast-float, pdf_oxide/lzw, acadrust/paste) instead of allowing AGPL, unmaintained, or RUSTSEC-advised crates into the production graph.

This PR is intentionally draft because it is a large platform tranche. The local GitHub CLI token is invalid, so this PR was opened through the connected GitHub app after SSH push succeeded.
