DSLO v0.7 — Add Substrate Metadata (metadata/substrate.json)

Added the substrate-level metadata file (metadata/substrate.json) for the DSLO v0.7
Hugging Face ingestion mirror. Hugging Face does not support real directories, so the
file is named with its directory prefix to preserve DSLO’s substrate topology. This
file defines substrate behavior, geometry bindings, invariant application, and lawful
transition modes across biological, cultural, abstract, physical, machine-facing, and
public-facing (tnopsi) surfaces. Provenance for this substrate metadata surface is
documented here in GitHub.

### metadata/substrate.json

Defines the DSLO v0.7 substrate-level metadata, including substrate behavior, geometry
bindings, invariant application, and lawful transition modes across biological,
cultural, abstract, physical, machine-facing, and public-facing (tnopsi) surfaces.
This metadata layer provides ingestion engines with a unified view of DSLO’s substrate
topology. Hugging Face does not support real directories, so the file name preserves
DSLO’s directory structure for ingestion engines.
