Subject: [PATCH] Update fuzz-utils.mjs and complete weekly fuzzing task

- Enhance scripts/agent/fuzz-utils.mjs with timestamped reports and configurable iterations
- Execute fuzz-dmDecryptor.mjs, fuzz-magnetUtils.mjs, and fuzz-nostrEventSchemas.mjs (10k iterations each)
- Log successful completion with 0 failures

+# Fuzz Agent Completion Log
+
+**Date:** 2026-02-20
+**Agent:** fuzz-agent
+**Status:** Completed
+
+## Summary
+Executed robustness fuzzing on `dmDecryptor`, `magnetUtils`, and `nostrEventSchemas`. Ran 10,000 iterations for each target. No failures were found.
+
+## Improvements
+- **`scripts/agent/fuzz-utils.mjs`**:
+    - Added timestamp to report filenames to prevent overwrites.
+    - Added `FUZZ_ITERATIONS` environment variable support for configurable test depth.
+    - Ensured robust directory creation for artifacts and reproducers.
+
+## Verification
+- **Command:** `FUZZ_ITERATIONS=10000 node scripts/agent/fuzz-<target>.mjs`
+- **Result:** SUCCESS. All reports (34 files) confirm 0 failures.
+- **Artifacts:** stored in `artifacts/fuzz-report-*-20260220.json`.
