feat(example): migrate to infospace config with tooling integration (S3.1)

Add infospace.yaml declaring topic, disciplines, schemas, viability
thresholds. Integrate infospace tooling into process_chapters.py with
--infospace-status, --infospace-check, and --infospace-viability flags.

Initial check: 85 entities, 4/5 viable (coverage 0.36 < 0.50 — only
7/35 chapters processed so far).
