Function load_config

Load configuration with priority support. Priority order (highest to lowest): 1. Environment variables (always highest priority) 2. Local .env file (ONLY in per-repo mode or when CGC_LOAD_PROJECT_ENV=1) 3. Global ~/.codegraphcontext/.env BUG FIX: In global/named context

    Load configuration with priority support.
    Priority order (highest to lowest):
    1. Environment variables (always highest priority)
    2. Local .env file (ONLY in per-repo mode or when CGC_LOAD_PROJECT_ENV=1)
    3. Global ~/.codegraphcontext/.env
    
    BUG FIX: In global/named context mode, local repo .env files are now properly ignored
    to prevent silent database redirection when working inside cloned repositories.
    
    Note: Does NOT create config directory - caller must call ensure_config_dir() first if needed.
