feat(RNPSW): automatically request maintainer reviews

[lstsavr]

Description

Adds a minimal-permission GitHub Actions workflow that automatically requests reviews from @just1and0 and @mosoakinyemi when a pull request is opened or marked ready for review.

The workflow:

• waits for draft pull requests to become ready for review;
• avoids requesting a review from the pull request author;
• avoids duplicate review requests; and
• does not check out or execute code from the pull request.

Issue URL

Closes #258.

Before and After

Before	After
Reviewers must be added manually, so pull requests can be missed.	The designated maintainers are requested automatically when a pull request is ready for review.

Permissions and security

The workflow grants only contents: read and pull-requests: write. It uses pull_request_target so review requests also work for pull requests from forks, but it never checks out or executes contributor-controlled code.

Validation

• Parsed the workflow as YAML and verified its event and permission structure.
• Checked the embedded actions/github-script JavaScript syntax.
• Ran the existing Jest suite: 16 tests passed.

Thanks for working in this. We've needed it for some time now. I will review ASAP.

Also this is still a draft PR, can you open it ?
