fix: address code review issues

- Fix 'nothing' check to consider hooks_to_remove and configs_to_remove
- Fix potential panic with multibyte chars in hook detection
- Fix incorrect 'removed' message when config removal fails
- Move git_config_get to utils to avoid duplication
- Optimize get_configured_keys: use git config --list (2 calls vs 10)
- Fix useless test assertion
