Ensure proper exit codes for all error conditions

- Exit with code 1 when no action is specified (show usage)
- Remove redundant failedRepos tracking since we stop on first error
- Simplify code by removing unnecessary failure tracking arrays
- Add test script to verify exit code behavior
- All errors now consistently exit with code 1
- Successful operations exit with code 0
