profile-run

Runs this project under a profiler and analyses what comes out — a benchmark, a test, a load script or the application itself, recorded with JFR or async-profiler, imported into a running Jeffrey Microscope and handed to analyze-jfr. Use whenever the user wants to profile something that is not recorded yet: "profile this benchmark", "record a JFR while the tests run", "why is this slow" with no recording in hand, or when a hotspot needs measuring rather than guessing — and when they ask how to record what a recording lacks: which JFR settings or async-profiler events capture exception types, locks, allocation or wall-clock time, per JDK version ("how do I record the exception types next time").
