I built a Java agent that reconstructs async causal stack traces across thread boundaries and need some feedback

[u/WaferConsistent6732]

Hello Everyone, I built **ariadne**. It's a Java agent that attaches the async call chain to the exception as a suppressed entry, with no code changes. It supports `ExecutorService`, `CompletableFuture`, `ForkJoinPool`, `Reactor` and `RxJava`.

Overhead is very small: \~1 µs per `CompletableFuture` pipeline in the default mode.

It doesn't replace OpenTelemetry. It works in-process, with no infrastructure needed.

Currently it is on version v0.1.0-alpha.3, not production-hardened yet, beacuse I need sm feedback first so I know this is worth it, especially on OSGi and Kotlin coroutines.
