load-tests

Run the VibeTags benchmark harness in load-tests/ and report the numbers honestly — annotation-volume and memory sweeps, JMH hot-path and cache-hit microbenchmarks, the processor-tax control — then record a release baseline under load-tests/results/. Use when the user says "load tests", "benchmarks", "capture a baseline", "did this get slower", "JMH", "performance regression", or before cutting a VibeTags release.
