refactor(docs): strip residual Phase/Plan setup-history references

Final sweep for setup-process bookkeeping not caught by template-reset-v1.
ADRs drop Plan-N qualifiers; spec collapses the historical 11-phase
migration table; scaffolding guide drops "Phase added" column; comment
prefixes referencing R-numbers in test describes / eslint inline comments
are normalized. Architecture-level rule IDs (R40, R52, E0, J0, etc.) are
preserved where they serve as stable cross-references in ADRs.

 - Two queue implementations means dev-seed handlers register via `queue.register(slug, ...)` while production relies on Payload tasks resolving from the per-feature container. The dispatch story differs by environment; the abstraction hides it but it's a real surface.
 - `InMemoryEventBus` is synchronous; `PayloadJobsEventBus` is asynchronous and at-least-once. Subscribers must be idempotent.
 - Six anchor comments in every feature is more visual noise than the average reader expects. Mitigated by the CI guard (so they can't drift accidentally) and the generators (so contributors don't need to know they exist).

-## Notes from execution
+## Implementation notes
 
-- **Plan paused at the Phase 5/6 seam, not at a failure.** Phases 1–5 (additive — new packages, new lint rules, new anchor comments) finished cleanly. Phases 6–9 (invasive — every binder signature, every app's bindAll, generators, proof-of-life, docs) ran in a continuation session.
-- **`InMemoryJobQueue.register()` was already in scope at Task 5** (`feat(core-shared/jobs): InMemoryJobQueue with register()`) so Task 34 Step 3's "add register" sub-step was already complete by the time bindAll-wiring landed.
 - **Auth is username-based, not email-based.** The spec's example contract had `email`; this ADR's `userSignedUpEvent` schema does keep `email`, but `signUpUseCase` synthesizes `${username}@example.local` to satisfy the contract. The proof-of-life flows record this synthesized email — the realism of the address is incidental to the cross-feature plumbing being verified.
 - **`apps/auth/src/di/module.ts` (the default-fallback DI module) gains `new InMemoryEventBus()` per `.toDynamicValue()` resolution.** Real cross-feature wiring runs through `bindProductionAuth` / `bindDevSeedAuth` where the bindAll-resolved bus is shared; the module's per-resolution bus is acceptable because the module is a default-mock fallback, not a runtime path.
 - **`@repo/auth` and `@repo/marketing-pages` exports were extended** for the e2e test: `./di/container`, `./di/symbols`, plus `marketing-pages` exposes `./services/mailer` and `./services/recording-mailer`. Containers and symbols being public is consistent with the binders already being public.
-- **Generator-level fixes folded in during Phase 8:** dropped publisher prompt's `when` clause (Plop `--args` cannot bypass conditional prompts); switched event-task template to `TaskConfig<{ input; output }>` shape (runtime slugs aren't keys of `TypedJobs['tasks']`); registered a custom Handlebars `eq` helper for the void/typed branch in `gen job`'s template.
