JVM Profiling Follow ups

Description

We have released JVM Profiling in https://github.com/getsentry/sentry-java/releases/tag/8.23.0

There are still tasks /improvements we could do:

• Docs (https://github.com/getsentry/sentry-java/issues/4909)
• Release registry entries
• Add module to .craft.yml
• Verify caching behaviour of ServiceLoader is not an issue (i.e. does not cause a large overhead on each chunk) - otherwise cache (obsolete with getsentry/sentry-java#4815)
• Remove / reduce vendored code and replace what's possible with JFR converter, also see https://github.com/async-profiler/async-profiler/issues/1525 getsentry/sentry-java#4852
• Upgrade async-profiler to 4.1+ to support newer Java Versions (23+); there are issues with a Converter dictionary (getsentry/sentry-java#4853)
• Log a specific message why Profiling isn't enabled if the wrong config property for setting sample rate is used (profiles-sample-rate) on JVM
• Enable / showcase Profiling in (more of) our samples getsentry/sentry-java#4941
• Allow configuring profilingTracesHz via sentry.properties (ExternalOptions)
• Add a .cursor rules file to explain how Profiling works getsentry/sentry-java#5034
• Fix an issue where the profilerId would not be propagated to SentryTracer correctly when used with OTEL Agent (getsentry/sentry-java#4854)
• Fix an issue with profiler initialization when using spring or spring-boot in OTEL Agent auto-init mode (getsentry/sentry-java#4855)
• Add profiling option to build plugins:
  • Gradle
  • Maven (https://github.com/getsentry/sentry-maven-plugin/issues/221)

Maybe later

• We could reduce profile chunk size / duration based on thread count of the application. This could help in case profiles are dropped due to being too large. Thread.activeCount() or ThreadMXBean (more accurate)
• https://github.com/getsentry/sentry-java/issues/4768 (we should wait for feedback first, maybe we don't need this)
• https://github.com/getsentry/sentry-java/issues/4779
• Detect that async-profiler is the (major) version we expect on startup, crash otherwise
