Greptile Overview

Greptile Summary

This PR updates the pull request template (.github/PULL_REQUEST_TEMPLATE.md) to add a new "Review Process" section that documents the introduction of AI-based code review tools. The change is purely informational and does not affect any code, dependencies, or workflows. It clarifies that all PRs still require human review by the PhysicsNeMo team, explains that AI tools like Greptile may provide automated comments with confidence scores (which indicate merge readiness but are not qualitative judgments), and encourages contributors to provide feedback on AI comments using reactions. This change improves transparency around the contribution workflow and sets appropriate expectations for contributors encountering automated review feedback.
