Add MCP tool annotations (readOnlyHint, destructiveHint, idempotentHint) to tools in the everything server, which serves as a reference implementation for MCP features. Updated tools: - echo: readOnly, idempotent (pure function) - get-sum: readOnly, idempotent (pure computation) - get-env: readOnly, idempotent (environment lookup) - get-tiny-image: readOnly, idempotent (static image) - get-annotated-message: readOnly, idempotent (message formatting) - get-structured-content: readOnly, idempotent (content generation) - toggle-simulated-logging: not readOnly, not idempotent (state toggle) This aligns the everything server with other MCP servers (filesystem, fetch, memory, git, time) that already include tool annotations.
