Add ai-ready external plugin

[johnpapa]

What

Adds the ai-ready external plugin to the awesome-copilot marketplace — a Copilot CLI skill that analyzes any repository and generates AI-ready configuration assets.

What it does

When a user says "make this repo ai-ready", the skill:

1. Auto-discovers GitHub context (zero user input) — repo metadata, language breakdown, community health, contributors, PR review patterns, CI workflows
2. Mines PR review comments for repeated feedback → turns maintainer review fatigue into automated conventions in copilot-instructions.md
3. Analyzes the codebase — manifest files, test setup, directory structure, existing AI config, changelog health, documentation setup
4. Generates customized assets — AGENTS.md, copilot-instructions.md, copilot-setup-steps.yml, CI workflow, issue templates, README contributing section, maintenance matrix, and more
5. Displays an AI-Readiness Report — score with progress bar, what was created/skipped/suggested
6. Offers an opt-in AI-Ready badge — Shields.io badge for the README + ai-ready GitHub topic

Why

Contributors (human and AI) don't know a repo's conventions. Maintainers waste time re-teaching them in every PR review. AI agents compound this — more PRs, same quality gap. This plugin closes the gap by teaching AI how to work in the repo correctly.

Technical details

• Skill-only — no extensions, no MCP servers, no arbitrary code execution
• GitHub-native — uses GitHub MCP tools and gh CLI to auto-discover context
• Uses only Copilot CLI's built-in tools (glob, grep, view, create, edit, bash)
• Never overwrites existing files — only fills gaps
• Self-consistency rule: generated files follow the conventions they establish

Closing in favor of a new approach — submitting as a lightweight wrapper skill instead of an external plugin. The wrapper installs the full skill from johnpapa/ai-ready, keeping the content in my repo while making it discoverable here. New PR incoming.
