Merge milestone/v1.14-refinement — v1.14 complete (NFR Refinement: bug fixes, security, stubs, tests, docs; 20 phases + final; tag v1.13.24)

v1.14 NFR Refinement milestone complete. 20 execution phases (P1-P20) +
1 final (P21). All P1/P2 backlog from v1.11 review resolved. Security
posture hardened (swallowed errors, account ID externalized, IAM scoped,
schema validation, credential hygiene). Stubs resolved (kyverno --kube-
version removed). 7 untested scripts gained coverage. Documentation
synced (ARCHITECTURE v1.11-v1.14 addenda, stale @v1.6-1.9 -> @v1.13,
GRILL G-005/G-008 resolved, COST.md window extended, D-083 deferral
recorded). Platform VPC parameterized.

561 tests pass (was 528 at v1.13.2; +33). 22/22 capabilities Verified.
6 grill binding decisions (G-101..G-106) applied. 1 escalation (E-001)
auto-resolved at full autonomy (D-101).
