Subject: [PATCH] Cleanup main task with iterator, improvements to git and
 composer handling

Cleaned up composer handling: Now checks if composer is already there and updates if needed. Made main task more readable.
Introduced iterator for path/symlink creation. Added optional .git dir removal for releases - keeps disk usage lower for large repos.
