## Goal

Introduce a `wireUseCase(...)` helper in `@repo/core-shared/conformance/` that encapsulates the `withSpan + withCapture (+ optional withAudit)` composition. Refactor all five features' binders to call the helper. Update the feature generator templates to emit the new call shape by default.

## Why

Five of `pnpm fallow`'s top-ten clone groups come from binder pairs across features. The inline wrapping runs 30–79 duplicated lines per binder pair. The helper becomes the single source of truth for the wrapping shape; per-feature binders shrink to their decision content plus a list of `wireUseCase` calls.
