[AZ-485] [AZ-486] Phase B Step 9: F4 barrels + F7 endpoints task specs

Closes Step 9 New Task cycle 1. Two refactor tasks created under epic
AZ-447 to address architecture compliance baseline findings:

- AZ-485 (5 pts) — F4 Public API barrels per component + STC-ARCH-01
- AZ-486 (5 pts) — F7 endpoint builders (endpoints.ts) + STC-ARCH-02
  (depends on AZ-485; Jira "Blocks" link set)

F1 (mission-planner duplication) deliberately deferred. Baseline routes
it through 7+ Phase B port-group cycles requiring decompose pass into
its own Epic; out of scope for new-task.

_autodev_state.md advances to Step 10 (Implement), awaiting invocation
for AZ-485 first.

+- Phase B started. Step 9 (New Task) cycle 1 closed:
+  - AZ-485 (F4 — Public API barrels + STC-ARCH-01, 5 pts, no deps)
+  - AZ-486 (F7 — Endpoint builders + STC-ARCH-02, 5 pts, blocked by AZ-485)
+  - F1 (mission-planner convergence) deliberately not created — needs `/decompose` for 7+ port-group cycles in its own Epic.
+- Step 10 (Implement) starts with AZ-485 — `Blackbox Tests` owns the static-check addition and the `tests/**` import-path migration; production component teams own their barrel files per `module-layout.md`.
