[RFC]: Complete float16 support across the @stdlib/array namespace

[gururaj1512]

Description

This issue tracks the work required to complete first-class float16 data type integration across the @stdlib/array namespace.
Foundational core registries (such as dtypes, dtype, ctors, safe-casts, and promotion-rules) have already been updated to support the new float16 type. Because of this:

1. Only 3 packages require runtime code modifications (logic changes) to support float16.
2. All other pending packages work automatically at runtime via delegation to the already-updated foundational utilities. However, they still require JSDoc example additions, TypeScript declaration updates (docs/types/index.d.ts), README modifications, and test suite coverage expansion to explicitly verify and document float16 / Float16Array support.
   Below is the complete hierarchical and alphabetical list of packages in the namespace, annotated with their status and task type.
