Subject: [PATCH] fix: CLI now properly rejects unknown commands

- Add handleUnknownCommand() helper function
- Add else clauses to 'i' and 's' switch cases
- Commands like 'invalid_command', 'infoooo', 'syncccc' now properly rejected
- Prevents silent acceptance of invalid commands
- Test TestCLICommandsE2E/CLIErrorHandling now passes
