[Bug] Local project settings bleeding into global ~/.claude/settings.json during REPL config browsing

Bug Description
I cannot explain what triggers it, but I've noticed multiple times ~/.claude/settings.json gets populated with extra lines (permissions -> allow block) that absolutely come from a particular project's .claude/settings.local.json

I have a feeling that happens when I start browsing settings in REPL. Either /config or /permissions or smth along those lines, or choosing "yes and allow during this session". The user's settngs.json gets bloated with project-specific stuff from multiple projects (where I have distinctive sets of rules).
