Subject: [PATCH 1/3] feat: add @stdlib/constants/float16/apery package
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add half-precision (float16) approximation of Apéry's constant
- Value: 1.2021484375 (correctly rounded ζ(3) from 1.202056903159594)
- Include complete documentation, tests, and TypeScript definitions
- Follow stdlib conventions and structure
