Critical fixes: - CRIT-009: Document lifetime constraint on LoginEvent references to prevent use-after-free (architectural fix requires larger refactor) - CRIT-015: Add proper libuv handle cleanup with uv_walk() before uv_loop_close() to prevent resource leaks High priority fixes: - HIGH-012: Log warning when LineReader truncates oversized lines - HIGH-013: Add division-by-zero check in Job::setTarget() for malformed target values - HIGH-016: Add MAX_UPSTREAMS limit (1000) in NonceSplitter to prevent unbounded memory growth under DoS conditions 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
