Restructure the TUI specification from a nested subsection under
"Behavior > UI / Interaction Model" to a top-level "## TUI" section,
giving it equal standing with Core Concepts, Behavior, Configuration,
and Architecture. All headings within the TUI section are promoted one
level (#### → ###, ##### → ####).
Fix mkdocs build nav warnings by adding ADR-044/045/046 to the
mkdocs.yml nav and registering three missing reference pages
(acms_fusion, context_indexing, resource_type_inheritance) in the
gen_ref_pages.py nav builder.
Implemented namespace/project/plan/skill permission model with role
bindings (owner/admin/editor/viewer) and default deny policy. Added
enforcement hooks at CLI/service boundaries that are server-only; local
mode returns permissive defaults. Includes role enums, permission check
service, role matrix documentation.
Includes Behave BDD scenarios, Robot integration tests, ASV benchmarks,
and reference documentation.
ISSUES CLOSED: #344
Added decision_model, resource_handlers, and resources to the manually-authored
reference page nav entries in gen_ref_pages.py so mkdocs no longer warns about
pages existing in docs/reference/ but not included in the nav.
