… lookup in voter APIs Replaced `Array.prototype.includes()` inside array `.filter()` loops with `Set.prototype.has()` in the voter addition and removal APIs (`src/routes/api/proposals/voters/add/+server.ts` and `src/routes/api/proposals/voters/remove/+server.ts`). This solves an O(N*M) time complexity issue when checking large arrays. Co-authored-by: yeboster <[email protected]>

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

💡 What: Replaced
Array.prototype.includes()inside array.filter()loops withSet.prototype.has()in the voter addition and removal APIs (src/routes/api/proposals/voters/add/+server.tsandsrc/routes/api/proposals/voters/remove/+server.ts).🎯 Why: The original implementation iterated over an array and performed an O(N)
.includes()lookup for each element, leading to O(NM) time complexity. As the number of domain owners and voters grows, this significantly slows down the API.📊 Impact: Expected performance improvement changes complexity from O(NM) to O(N+M). This drastically reduces CPU utilization and response time for large datasets.
🔬 Measurement: Verify by executing the unit tests (
pnpm test:unit --run) and optionally benchmarking the/api/proposals/voters/addand/api/proposals/voters/removeendpoints locally with large mocked arrays to observe the execution time reduction.PR created automatically by Jules for task 13373394845453975963 started by @yeboster
