This PR introduces a kernel-side mechanism to filter internal kernel module frames from the debugger callstack.
These frames currently appear when stepping (e.g. pressing “Next”), causing the debugger to stop deep inside IPython internals and creating long, noisy callstacks.
This PR also flips
debug_just_my_codetoFalseby default to allow users to debug external sources when needed, and introduces a kernel-side filtering layer that hides internal kernel frames unless explicitly disabled.Without filtering:
