PythonInfoCollector._get_tcl_tk_libs()created a Tcl interpreter while reading library paths. WithTCL_LIBRARYset andHOMEabsent, that could run a startup file from the caller's working directory as the caller. The probe now skips Tk startup profiles. This addresses draft advisory ANT-2026-KHIWVYIK.Tk profile execution
tkinter.Tcl()creates aTkobject. Its initializer callsreadprofile(), which loads profile files fromHOMEor the working directory. The collector now supplies a profile-free Tk subclass withuseTk=False, retaining the Tcl library query without executing profile files.Behavior changes
Interpreter discovery no longer runs Tk profile files while detecting Tcl/Tk libraries. The library paths remain available when tkinter supplies them; missing tkinter or a Tcl error still leaves those paths unset.
