refactor(git): improve default branch detection in git_main_branch function

Browse source 
Reorganized the `git_main_branch` function to first attempt to retrieve the default branch from remote HEAD symbolic refs for both `origin` and `upstream`. This change enhances the reliability of branch detection by prioritizing symbolic references before falling back to common branch names. The function still defaults to "master" if no main branch is found, maintaining backward compatibility.
