Function ExecuteCommand 

pub fn ExecuteCommand(
    CommandIdentifier: String,
    Argument: Value,
) -> ActionEffect<Arc<dyn CommandExecutor>, CommonError, Value>

Creates an effect that, when executed, will run a command by its unique identifier.

It uses the CommandExecutor capability from the environment to dispatch the command to the appropriate handler, whether that handler is a native Rust function or a proxied function in an external sidecar process.

Parameters

• CommandIdentifier: The unique ID of the command to execute (e.g., “FileSystem.ReadFile”).
• Argument: A serde_json::Value containing the arguments for the command.

Returns

An ActionEffect that resolves with the command’s return value as a serde_json::Value, or a CommonError if the command is not found or fails during execution.
