…search Removed intermediate array allocations via `flatMap` and spread syntax in the frontend's `App.tsx` search filtering logic. Replaced with direct string concatenation to significantly reduce garbage collection pressure and maintain smooth 60fps rendering during high-frequency keystroke events across large ERD graphs.

💡 What: Replaced
flatMap(),join(), and array spread syntax with direct string concatenation when computing the searchhaystackin the frontendsearchMatchedNodeIdshook.🎯 Why: The previous approach allocated multiple temporary arrays per node on every re-render while searching. For large ERD diagrams with hundreds of tables and columns, this resulted in massive memory churn and garbage collection spikes, blocking the main thread during high-frequency typing events in the search bar.
📊 Impact: Reduces memory allocations per node from O(C) array allocations (where C is columns) to exactly one string allocation, drastically lowering GC pressure and dropping search computation time, which should enable smooth 60fps updates while typing even on complex graphs.
🔬 Measurement: Confirmed identical search functionality via
pnpm run testwhich passes without regressions. The performance impact can be verified by observing reduced GC pauses and lower memory allocation in Chrome DevTools Performance tab when typing rapidly into the canvas search bar with a large populated ERD.PR created automatically by Jules for task 2566554658559866642 started by @seonghobae
