Rspack Debugging

When Rspack crashes with a segfault or hangs during builds, this gives you a structured way to capture what's actually happening under the hood using LLDB. It handles the annoying parts automatically: swapping in debug symbol packages, setting up non-interactive debugging sessions, and routing you to the right workflow based on whether you're dealing with HMR crashes, build hangs, or those maddeningly intermittent deadlocks. The coredump analysis guides are especially useful for bugs you can't reliably reproduce. Just remember to save your backtraces to the debug_artifacts folder before your session ends, and restore your production packages when you're done.
