PR review bot

Why make this change?

Automate PR reviewer assignment to distribute review workload evenly across the team instead of relying on manual assignment or CODEOWNERS (which adds all owners).

What is this change?

Adds auto-assign-reviewers.yml, a label-driven GitHub Actions workflow that assigns exactly 2 reviewers per PR using load-balanced selection.

High-level workflow steps-

1. Fetches all open PRs → filters to eligible ones (label + non-draft + fresh)
2. Reads pr.assignees for each PR → determines who's already assigned
3. Calls listReviews for PRs with assignees → determines who's actively reviewing vs freed
4. Builds load map from scratch → sums active review weights per reviewer
5. Assigns based on current state

How is this tested?

• Tested with DRY_RUN and non-DRY_RUN mode and validated the assigned reviewers.

Pull request overview

Adds a GitHub Actions workflow intended to automatically assign reviewers to PRs based on labels and a simple load-balancing heuristic.

Changes:

• Introduces .github/workflows/auto-assign-reviewers.yml to select and request reviewers when PRs are opened/updated/labeled.
• Implements label-based eligibility (assign-for-review) and weighting (size-*, priority-high) to prioritize larger/higher priority PRs.
• Tracks current reviewer “load” across open PRs to pick the least-loaded candidates.

Idea is good, but missing testing to ensure this actually works.
