refine-issue skill

Fetch a GitHub issue by number and rewrite it to a consistent template. The skill reads the issue, optionally reads the codebase for context, then produces a structured version with a gitmoji-prefixed title, 🎯 Problem, 📋 Description, ✅ Acceptance Criteria, and more. Shows a before/after diff before updating.

features

• fetches issue title, body, and labels via gh issue view --json
• reads codebase (git ls-files + key files) to enrich Technical Notes and validate acceptance criteria
• rewrites to the same template used by /create-issue: gitmoji title, 🎯 Problem, 📋 Description, ✅ Acceptance Criteria, 🔁 Steps to Reproduce (bugs), 💡 Technical Notes
• preserves any good content already in the issue — rewrites structure, not ideas
• proposes an improved title only when the existing one is too vague (e.g., "fix bug", "update")
• shows a before/after diff and waits for confirmation before posting
• --dry-run prints the gh issue edit command without executing it
• updates in-place via gh issue edit
