Sync the application path with the shell

[cthrall]

Summary

When the application is launched from the Finder in Mac OS, the path that is passed to the application is the launchd path (/usr/bin:/bin:/usr/sbin:/sbin). It's possible that command-line tools like Git are installed elsewhere. This change uses the crate fix-path-env-rs to sync the application path with the user's shell path.

Test Plan

• Launch Maestro from the Finder in Mac OS on a computer where Git is installed somewhere that is not in the launchd path and start an agent session that creates a new worktree.
