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

### 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.

### Checklist

- [x] I have read and understood the [Code of Conduct](https://github.com/stdlib-js/stdlib/blob/develop/CODE_OF_CONDUCT.md).
- [x] Searched for existing issues and pull requests.
- [x] The issue name begins with `RFC:`.

Start by reviewing the unchecked packages in the @stdlib/array/base/assert namespace and the related package entries in the checklist, then inspect the existing implementations, tests, README files, and docs/types/index.d.ts. Run the affected package test suites to establish current behavior. Done means the remaining float16/Float16Array documentation, declarations, and test coverage are complete, with runtime changes only where the checklist requires them.
