add-api-route

# Add an API route Follow the conventions in `.claude/rules/api.md` (response schemas, `z.date()`, global error envelope). Steps: 1. Request schema: reuse or add in `packages/contracts` (or the module's `<name>.schema.ts`). Uuid path ids via `idParam`. 2. Response schema: model the service's return **exactly** in `<name>.schema.ts`, or use a shared envelope from `@/types/response`. Elysia strips fields not in the schema. 3. Route: in `modules/<name>/<name>.controller.ts`, add `body`/`query`/`params` as needed, the `response` success schema, a `detail` summary, and a `rateLimit(policy)` `beforeHandle` where the endpoint warrants one. No per-route error responses - they're declared globally. 4. Logic in `<name>.service.ts` (tsyringe `@singleton`; injected classes stay value imports). New module: mirror an existing one and mount its controller in `app.ts`. 5. Web side (if needed): Eden Treaty picks up types automatically; add query/mutation hooks under `apps/web/src/api/`. 6. Invoke the `verify` skill.
