    rename default branch from 'master' to 'main' in refs and test scripts
    
    This patch updates Git's default branch name from 'master' to 'main' to
    align with modern naming conventions adopted across the industry.
    
    The change affects only newly initialized repositories and maintains
    full backward compatibility through the existing init.defaultBranch
    configuration option.
    
    Changes made:
    
     * refs.c: Update hardcoded default branch name to 'main'
     * remote.c: Update fallback branch name for remote operations
     * t/test-lib.sh: Update test suite default to 'main'
    
    Compatibility notes:
    
     * Existing repositories are unaffected
     * Users can still set init.defaultBranch=master if preferred
     * The change only applies to new git init operations when no explicit
       branch name is configured
    
    This follows the precedent set when init.defaultBranch configuration was
    introduced in Git 2.28, which already acknowledged the community's move
    toward more inclusive default branch names.
