QUALITY-SCORING.md exists but no automated quality checker applies it

[StencilwashCoder]

The QUALITY-SCORING.md document describes a quality scoring rubric for plugins, but there's no automated scoring tool or CI integration that actually applies these criteria to incoming plugins.

Plugin authors have no feedback on whether their submission meets the quality standards before opening a PR. Reviewers must manually evaluate each plugin against the rubric, which is inconsistent and time-consuming.

An automated quality checker (even a simple script) that scans new plugin submissions and reports on:

• README completeness
• Required file presence (LICENSE, plugin.json, etc.)
• Description clarity and length
• Code quality basics

Would dramatically improve the review process and set clear expectations for contributors.
