Replaces multiple chained `O(n)` array operations (`Object.entries().filter().map()`) in `src/analyzers/dkim.ts` with a single-pass `for...in` loop. This avoids allocating and discarding multiple intermediate arrays (like the entries array, the found array, and the mapped strings arrays) on the critical path, significantly reducing Garbage Collection (GC) pressure and improving overall memory efficiency during DKIM analysis without sacrificing readability.

💡 What: Replaced chained array methods (
Object.entries().filter().map()) with a single-passfor...inloop insrc/analyzers/dkim.ts.🎯 Why: To reduce intermediate array allocations (like the
Object.entriesarray, the intermediate.filterarray, and the subsequent.mapstrings array) that cause unnecessary memory overhead and Garbage Collection (GC) pressure on the critical path during DKIM analysis.📊 Impact: Avoids creating up to 8 intermediate arrays per DKIM analysis run, providing a minor but measurable reduction in peak memory allocation and GC churn for the Hono worker environment.
