v0.3.0

✨ What’s new

• In-memory caching for GitHub App label lookups (reduces API calls + faster repeat searches)
• Cache transparency in API response (cache.hit, cache.cached_at)
• API request tracking flags (api.unauthenticated_hit, api.authenticated_hit)
• Dual rate-limit reporting for unauthenticated vs authenticated GitHub API requests

🧠 Improvements

• More reliable fallback flow when slugs cannot be resolved
• Frontend shows clearer status indicators (cached vs fresh, fallback, rate-limit)
• Updated README documentation with full API response reference table
• Schema file updated to match the current API response structure

⚠️ Notes

• Cache is in-memory only (clears when the backend restarts)
• GitHub rate limits can still apply, but caching greatly reduces repeated hits
