Present Dknowledge as distributed memory - #7

…consolidation

- value-management-ecosystem.md, support-model.md and CURRENT.md: synthesis alone
  does not authorize an action; constitutional constraints, security, permissions,
  integrity, reserves and risk bound what Dk proposes. Effects and refusals return
  through personal Dks without a universal individual veto; a decision can be
  maintained, adapted, excepted, suspended or reversed. A general level summarizes
  integration; the trajectory remains the real source.
- roadmap/DIRECTION.md: remove residual economic formulation (transferable and
  non-transferable reputation kinds, value units, VME); Dktron as stable resource
  representation, Dk Personal as continuous representation.
- llms.txt: core concepts for safeguards, response circuit and security.
- data/catalog.json regenerated.
