This commit optimizes array filtering in `voters/add/+server.ts` and `voters/remove/+server.ts` by replacing the O(N) `Array.prototype.includes` lookups with O(1) `Set.has` lookups. This improves performance from O(N*M) to O(N+M) when operating on large lists of domain owners and proposal voters, mitigating main thread blocking during these API requests. The corresponding learning pattern has been documented in the `.jules/bolt.md` journal. Co-authored-by: yeboster <[email protected]>

💡 What: Replaced
Array.prototype.includes()withSet.prototype.has()inside theArray.prototype.filter()loops in thevoters/add/+server.tsandvoters/remove/+server.tsAPI endpoints.🎯 Why: Using
Array.includesinside afilterloop creates an O(N*M) time complexity. Given that bothowners(all domain owners) andvoters(current participants in a proposal) can be very large arrays, this previously blocked the main thread significantly. By precomputing aSet, the lookup becomes O(1), bringing the overall complexity down to O(N+M).📊 Impact: Reduces time complexity of the voter filtering operations from O(N*M) to O(N+M). This will result in substantially faster API responses and less server CPU utilization when processing large domain owner and voter lists.
🔬 Measurement: This can be verified by benchmarking the endpoint response times before and after the change with datasets simulating 10,000+ domain owners and voters. The reduction in execution time should be easily measurable using standard node profiling tools.
