[Bug] Sandbox policy violation: graphify tool accessing restricted /home/.msp.json path

Bug Description
Ran the /graphify skill on Claude Code (background job session). Every subsequent Bash tool call — including trivial ones like echo hello and pwd, unrelated to graphify itself — began failing with a sandbox (bubblewrap) permission error trying to create /home/.mcp.json, a path outside the sandbox's writable scope. The sandbox never recovered for the rest of the session; Bash was completely unusable afterward.
