Implemented a bounded CRM core slice (pure TS domain + in-memory API) and added the full required doc/artifact set.

- Domain logic: `packages/domain/src/index.ts`
- In-memory services: `packages/api/src/index.ts`
- Tests: `packages/domain/test/domain-core.test.ts`, `packages/api/test/api-core.test.ts`
- Docs + traceability + demo/QA flows: `docs/*`, `demo/crm.demo.yaml`, `qa-flows/crm-smoke.json`, `CHANGELOG.md`, `README.md`
