chore: apply the over-engineering audit's five cuts

[btravers]

Five findings from a repo-wide over-engineering audit, applied. Net −131 lines.

The cuts

• Ten byte-identical vitest.config.ts → one-line re-exports of a root
  vitest.shared.ts (nine examples + packages/di). Workspaces with real
  divergence — core's coverage thresholds, amqp's and the workers'
  globalSetup/cache configs — keep their own file: divergence stays visible in
  the workspace, not hidden in an override. knip ignores the shared file because
  the root package deliberately declares no vitest dependency.
• Two doc passages still described examples/order-worker, a workspace
  deleted before the rename. Thesis feat: the application kernel #1 now names the three runtimes that exist,
  with the outcome order corrected (api → CONFLICT, temporal → nonRetryable,
  amqp → dead-letter), and examples/README.md drops the ghost
  queueWorkerRuntime and states temporalWorkerRuntime's and
  orderAmqpRuntime's real needs ([Outbox, Logger] for the latter — the old
  text claimed [PlaceOrder, Logger] for all three, which was wrong twice over).
• .changeset/no-release-first-publish.md explained a decision in the di
  repository's release history; here it was a no-op file changeset version
  would consume into nothing.
• turbo.json's dev task drops ^db:migrate: dev exists only in the
  five published packages, none of which depend on order-infrastructure, so
  the edge could never fire.
• (Disk only) four untracked husk directories holding nothing but
  node_modules/.turbo deleted: packages/start,
  examples/order-{amqp,temporal,worker}.

Checked and deliberately not cut

createDeferred (looks like Promise.withResolvers, but the published
engines: ">=20" floor blocks it and the idempotent resolve is the point), the
32-file one-concept-per-file packages/core/src, and the
message-units.ts/activity-units.ts similarity across runtime packages —
the price of packages that don't import each other, which is a stated thesis.

Gate

format ✓ lint ✓ typecheck ✓ knip ✓ build ✓ test 21/22 — the one
failure is the known local port-9000 clash in packages/core, unrelated. All
ten suites on the shared vitest config pass.

Pull request overview

This PR applies several repo-wide “over-engineering audit” cleanups: it centralizes identical Vitest configuration, removes an unused changeset, simplifies Turbo task dependencies, and updates documentation to reflect the current example/runtime set.

Changes:

• Introduce vitest.shared.ts and switch multiple workspaces to re-export it from their vitest.config.ts.
• Remove an unused .changeset/no-release-first-publish.md and adjust turbo.json dev-task dependencies.
• Update docs (CLAUDE.md, examples/README.md) to remove stale references and correct runtime/needs descriptions.
