Closes #1311, #1837, #1339, #1848
Speedup the processing of evidence by starting multiple EvidenceHandlerWorker processes in parallel.
Optimize and refactor localnet detection logic.
Reduced the default number of profiler workers started at launch from 5 to 3, with the existing scaling logic still available.
Changed network discovery to consume new_flow events instead of tw_modified, to avoid depending on the pub sub published msgs per flows for portscan checks. (main latency bottleneck)
Added a generate_performance_plots parameter to enable/disable performance plots.
Added performance instrumentation for input, profiler workers, and evidence handling to record throughput and latency data in output/performance_plots/csv/.
Added a Plotter to generate plots on shutdown and log throughput/latency metrics to metrics.txt.
Added a stress-testing docs documenting baseline, sudden spikes and soak testing.
Handle divide-by-zero case in progress reporting in slips/main.py.
