Subject: [PATCH] refactor: use `constants/float64/nan` in
 `stats/base/dists/beta/mean`

Replace inline NaN generation in the C implementation with the shared
stdlib NaN constant. This removes a magic expression in favor of the
canonical constant and keeps NaN generation consistent across packages.

Add `@stdlib/constants/float64/nan` as a dependency to each manifest
configuration which compiles `src/main.c`.

Ref: #11743
