docs: refresh explainers + adding-a-feature with full binder signature

di-explainer and data-flow-explainer narratives still showed the
pre-ADR-014 1-arg bindProductionBlog(config) form. Updated both
explainers to (config, tracer, logger, bus, queue), and adjusted the
narrative arc so the production-swap step mentions the
resolveEventsAndJobs* preamble.

adding-a-feature's Step 16 sketch was the same 1-arg shape; replaced
with the canonical 5-arg signature and a short note that the bus/queue
params are accept-and-forward until gen event consume / gen job
generators inject usage at the anchors. Pointer to a real feature's
bind-production.ts for the complete reference.

Final sweep is clean — no stale (container, config) or 1-arg
bindProduction signatures remain in docs/.

 ### Step 16: `bind-production.ts`
 
+The full canonical shape includes instrumentation (ADR-014) and the
+event-bus + job-queue parameters (ADR-015) — see any feature's
+`bind-production.ts` for a complete reference. Minimal sketch:
+
 ```typescript
 // src/di/bind-production.ts
 import type { SanitizedConfig } from "payload";
+import {
+  withSpan,
+  withCapture,
+  type ITracer,
+  type ILogger,
+} from "@repo/core-shared/instrumentation";
+import type { IEventBus } from "@repo/core-events";
+import type { IJobQueue } from "@repo/core-shared/jobs";
 import { commentsContainer } from "./container";
 import { COMMENTS_SYMBOLS } from "./symbols";
 import { CommentsRepository } from "../infrastructure/repositories/comments.repository";
 
-export function bindProductionComments(config: SanitizedConfig): void {
+export function bindProductionComments(
+  config: SanitizedConfig,
+  tracer: ITracer,
+  logger: ILogger,
+  bus: IEventBus,
+  queue: IJobQueue,
+): void {
   if (commentsContainer.isBound(COMMENTS_SYMBOLS.ICommentsRepository)) {
     commentsContainer.unbind(COMMENTS_SYMBOLS.ICommentsRepository);
   }
+  const repo = new CommentsRepository(config, tracer, logger);
   commentsContainer
     .bind(COMMENTS_SYMBOLS.ICommentsRepository)
-    .toConstantValue(new CommentsRepository(config));
+    .toConstantValue(repo);
+  // Use cases + controllers are wrapped with withSpan(withCapture(...))
+  // at bind time. bus + queue are accept-and-forward until you add an
+  // event handler or job — at which point the gen event consume / gen job
+  // generators inject usage at the // <gen:event-handlers> / // <gen:jobs>
+  // anchors at the end of the function body.
 }
