Accurate tool safety hints for connected clients

memsprout's MCP tools now tell connected clients (Claude, ChatGPT) more precisely what kind of action each one performs — every tool is marked as operating only within your own memsprout data rather than the open web, and safe-to-retry actions like updating, moving, or deleting a memory are marked as such. Clients that respect these hints should prompt less aggressively before running memsprout's tools.
