💡 What: Refactored the parseAppInfo helper function in server/api/apps.ts to use .indexOf('=') and .substring() instead of .split('=') with array destructuring and .join('=').

🎯 Why: Using .split('=') and .join('=') creates unnecessary intermediate arrays and puts unnecessary strain on the garbage collector. Since parseAppInfo processes line-by-line in a loop for each app configuration fetched from the repository, avoiding array allocations provides a small, measurable reduction in O(N) allocation overhead per request.

📊 Impact: Reduces array allocations and GC pressure. When fetching from the REST fallback, this reduces the creation of numerous intermediate arrays, leading to less memory churn and marginally faster execution of the endpoint response caching.

🔬 Measurement: Run the app and hit the /api/apps endpoint. Validate that the returned data is identical and app info (like id, name, version, etc.) is fully populated. Additionally, verified by running pnpm build which uses the endpoint correctly without failing.
