[Bug] Shell snapshot duplicates hyphens in alias names causing tool errors

Question

**Bug Description**
The shell snapshot feature does not correctly handle aliases with `-` ~in the name~ in the command. The snapshot tool seems to duplicate the hyphens which cause the bash tool to report errors despite running successfully below the error. This has misled the agent on a few occasions. Removing the alias resolved the problem. Example: `alias -- -='cd ..'`. I introduce this alias via `.bashrc` but I believe the alias source to be unrelated.
