joernio/joern ? reverse-engineered prompt

Build me a developer tool for security research that can analyze source code, bytecode, and binary executables, then turn them into a graph that I can search for bugs and risky patterns.

I want it to support C, C plus plus, Java, JavaScript, Python, Kotlin, and binaries, with a command line workflow that can parse code, create the graph, run queries, and export results. It should feel like a serious bug hunting workbench, where I can load a project, inspect control flow and data flow, and write searches in a simple Scala based query language.

Please make it easy to run locally, and if you need to check anything, look up the current docs online. I also want a server mode for browsing and automation, plus a clean install path and tests so I can trust the build.
