Research direction
Investigate the command parsing logic in Multipass's CLI code, likely in files related to command execution. Review the comments in PR #1439 (linked in the issue) to understand the original context and expected behavior. Focus on how command strings are constructed and passed to the shell, especially around '$' escaping. Look for any existing tests for command escaping.
