Embed the NX Tcl Remote Debugger into the NX Postprocessor extension. Add a new debugging client, protocol, and adapter logic to drive attach/launch, breakpoints, stepping, and evaluation via the runtime adapter. - Introduced a client debugger with a new adapter and protocol - Wired attach/launch, breakpoints, stepping, and evaluation - Updated docs and licensing to reflect the embedded debugger
