Add command task execution and improve command documentation

Introduced a new CommandTaskContext structure to facilitate command execution in separate tasks. Updated the execute_command function to spawn tasks for commands, enhancing concurrency. Improved documentation for the 'memtest' and 'tasktest' commands in README.md to clarify their functionality and usage. Updated the interactive prompt reference to 'starling>'.
