Fix empty Storage section by properly aliasing command types

v0.1.220 broke disk collector by changing the import from
std::process::Command to tokio::process::Command, but lines 193 and
767 explicitly used std::process::Command::new() which silently failed.

Solution: Import both as aliases (TokioCommand/StdCommand) and use
appropriate type for each operation - async commands use TokioCommand
with run_command_with_timeout, sync commands use StdCommand with
system timeout wrapper.

Fixes: Empty Storage section after v0.1.220 deployment
Bump version to v0.1.221
