docs(plan-8): partial Lazar doc-update pass (CLAUDE.md, overview.md, ADR-012, Plan 7 annotations)

First slice of the Plan 8 deferred doc-update checklist:
- CLAUDE.md Key Conventions: factory-function use cases/controllers,
  entities/models/<x>.ts paths, .toDynamicValue DI bindings, direct
  injection in tests
- docs/architecture/overview.md data-flow box updated to factory style
  (controller resolved via container.get<IXController>; use case factory
  takes deps as args)
- docs/decisions/adr-012-lazar-conformance.md created — records the
  conformance decision and four intentional divergences
- docs/superpowers/plans/2026-05-05-plan-7-tdd-foundation.md and the
  matching spec annotated with a "pre-Plan-8 layout" note pointing at
  the refactor log

Remaining Plan 8 doc-update items (root AGENTS.md, per-feature AGENTS.md,
adding-a-feature.md, tdd-workflow.md, testing-strategy.md,
vertical-feature-spec.md §6/§10, core-testing AGENTS.md) intentionally
paused — Plan 9 (input/output unification) will change overlapping
content, so resuming after Plan 9 lands avoids double-churn.

 # Plan 7 — TDD Foundation Implementation Plan
 
+> **Note (2026-05-05, post-Plan-8):** All file paths in this plan reference the **pre-Plan-8 layout** (`mock-articles.repository.ts`, `entities/article.ts`, multi-method `articles.controller.ts`, etc.). The Lazar conformance refactor (Plan 8) renamed/reshaped these files. See `docs/superpowers/refactor-logs/2026-05-05-lazar-pattern-conformance.md` for the full mapping; ADR-012 documents the conformance decision.

 > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
 
 **Goal:** Make full TDD frictionless in this monorepo by closing the ten gaps catalogued in `docs/superpowers/specs/2026-05-05-tdd-foundation-design.md`.

 # TDD Foundation — Design Spec
 
+> **Note (2026-05-05, post-Plan-8):** File-path references in this spec describe the **pre-Plan-8 layout**. Plan 8 (Lazar pattern conformance) introduced `entities/models/`, `entities/errors/<domain>.ts`, the `.mock.ts` suffix, dropped `payload-` prefixes, and made use cases / controllers factory functions. The TDD principles, gap catalogue, and `core-testing` package design remain valid; only the example paths and snippets shifted. See `docs/superpowers/refactor-logs/2026-05-05-lazar-pattern-conformance.md` and ADR-012 for the mapping.
