Add WP-0030 delegation register; refresh INTENT and SCOPE

Founder directive: ops-warden works with, never replaces or duplicates,
secrets-engine / tenant-engine / user-engine. Covering an unfilled gap is
acceptable only as a tracked interim with a named intended owner.

- INTENT §9 "Cover gaps, but never silently own them"; success criterion 7;
  tenant-engine and user-engine added to the literacy table; non-goal on
  permanently owning another component's lane
- WP-0030 (proposed): delegation: metadata, backfill, warden route gaps,
  promotion gate, publish the register to owner repos
- history/2026-08-11-delegation-surface-assessment.md: 2 of 24 lanes carry
  exec_owner; 11 proxies record no intended owner
- SCOPE refreshed to 2026-08-11 (was 6 workplans behind); completeness C5 -> C4
