💡 What: Replaced the O(L * S) iteration loop over all lines and stations inside `getTransferableLines` with an O(1) map lookup using `buildStationIndex(railwayData)`. 🎯 Why: `getTransferableLines` is called frequently during trip editing and routing. Scanning through every single station in the massive `railwayData` object to find matching names caused a significant performance bottleneck. 📊 Impact: Reduces time complexity from O(L * S) to O(1) for station name lookups. 🔬 Measurement: Verified by running type checking (`npx tsc --noEmit`). Also appended this insight to the Bolt journal at `.jules/bolt.md`. Co-authored-by: OsakaLOOP <68284076+OsakaLOOP@users.noreply.github.com>
