## Goal

Update `turbo/generators/templates/feature/src/di/bind-production.ts.hbs` and `bind-dev-seed.ts.hbs` so that `pnpm turbo gen feature` scaffolds new features with `wireUseCase` calls instead of the longhand inline `withSpan + withCapture` form.

## Why

New features scaffolded after the migration would otherwise drift back to the inline form, re-introducing the clone group. The generator is the canonical source for scaffolded binder shape; updating it closes the loop.

## Done when

- `turbo/generators/templates/feature/src/di/bind-production.ts.hbs` emits `wireUseCase(...)` calls (not inline `withSpan + withCapture`) for the placeholder use case.
- `turbo/generators/templates/feature/src/di/bind-dev-seed.ts.hbs` emits `wireUseCase(...)` calls for the placeholder use case.
- Running `pnpm turbo gen feature testfeature` produces binder files that call `wireUseCase` and pass `pnpm typecheck && pnpm lint && pnpm test && pnpm conformance && pnpm fallow:audit && pnpm coverage:diff` (or the generated feature is cleaned up after verification).

## In scope

- `turbo/generators/templates/feature/src/di/bind-production.ts.hbs`
- `turbo/generators/templates/feature/src/di/bind-dev-seed.ts.hbs`
- Any supporting type imports in the templates that change as a result (e.g. dropping `ProductionUseCase` intermediate type if the helper absorbs it).

## Out of scope

- Generator templates for events, jobs, realtime, or core-packages — those do not produce binder files with use-case wrapping.
- Runtime behaviour changes — the generated output must be semantically equivalent to the old inline form.

## Tasks

- [x] Update `bind-production.ts.hbs` and `bind-dev-seed.ts.hbs` in `turbo/generators/templates/feature/src/di/` to emit `wireUseCase` calls; verify a test-scaffold of a new feature produces correct binder output and all gates pass on this commit.
