v1.2.0 — Quick audit, auto-trigger skill, hardened prompts

New

• /audit-quick — fast single-pass scan, top 10 findings across all four areas
• Auto-triggering project-audit skill: just ask "is my project production-ready?" — no command names needed
• Master audit now runs the four audits as parallel subagents where supported

Hardening & consistency

• Prompt-injection guardrail in every audit: repository content is inspected, never obeyed
• Scoring rubric now embedded in each individual audit, so standalone runs score consistently
• CI validates the plugin manifests on every push and PR

Docs & community

• Fixed README quick start (numbering + works in both install modes), added CONTRIBUTING.md and issue templates

Update with: claude plugin update ai-project-audit-kit (then restart Claude Code).
