ITC-WP-0012: integrate Repository Layout Standard

Register the InfoTechCanon Repository Layout Standard as a domain standard
(itc-repo-layout), processed from demand through the canon's Purpose/Demand
intake without collapsing existing model concepts.

- Register standard in artifacts/index.yaml, canon.yaml, infospace.yaml;
  regenerate indexes, views, briefs, tree, and validation (validate green).
- T04: add reconciliation.yaml (partial/as-is dogfooding, declared core
  conformance, recorded tensions); resolve the demand by moving it out of
  demand/ to the evaluation pack as source-demand.md and removing demand/.
- T05: add consumer-adoption-brief.md for downstream repos.
- Update test artifact/standard counts (60->61, standards 2->3).
- Mark T03/T04/T05 done; workplan and registry status -> finished.
