McpTools-listSchema-driftBreaking-changeAgent-compatibility

MCP schema drift and MCP tools/list compatibility gate for agent upgrades. Compares complete baseline and current snapshots; detects removed or renamed tools, new required arguments, incompatible input or output schemas, and model-facing metadata or safety-hint regressions. Returns an exact-hash compatibility verdict without fetching or invoking tools.
