### Command
generate
### Is this a regression?
- [ ] Yes, this behavior used to work in the previous version
### The previous version in which this bug was not present was
_No response_
### Description
Long story short is that the Angular CLI generate or g command is capable of doing some illegal and difficult to reverse file operations.
Longer version: I was going to create a component this morning to make building PrimeNG p-tables simpler and more dynamic. At the time I started, what I was thinking of was specific to a set of tables I intended to use in an administrative context, so I navigated to something like /src/modules/sales/costing-tool/components/templates and typed "ng g c admin-table".
Before I hit enter, I thought about it and decided that rather than creating a module and specific use component that I'd rather make a general use component for generating p-tables dynamically & that it belonged in a shared module rather than a feature module. I thought I'd already deleted the CLI command out of the terminal so without looking I typed cd.. and hit enter. Which was the beginning of a 2+ hour headache that ended up costing me 2 days of work and which potentially could've cost me all the work I've done since May 5.
So the command I effectively entered was "ng g c admin-tablecd..", and what happened is that the CLI was able to somehow dodge the OS level naming safety conventions & it created a folder named admin-tablecd.., which caused there to be an unresolvable reference in my project structure and made it unloadable and unbuildable. And there was nothing I could do to delete the offending folder. I tried deleting it through the UI, using DOS commands, using WSL commands including rmdir with the -rf flag, nothing would get rid of it, even after a reboot. I had just about resolved myself to having to clone my latest remote to a new local repo which would've set me back to the 5th when I tried rmdir with the "\\?\c:\path\to\bad\directory" syntax which finally worked.
I think that optimally the generate command should respect naming safety conventions, or minimally provide a complimentary command to remove generated components.
### Minimal Reproduction
Via the CLI, generate a component with a name that ends in a directory traversal operator, i.e. new-componentcd..
### Exception or Error
```text
The system cannot find the file or directory specified
```
### Your Environment
```text
Angular:

### Anything else relevant?
Can't think of anything.
Hướng dẫn đóng góp
Hướng nghiên cứu
Bắt đầu tại điểm vào của lệnh `generate` trong Angular CLI và tái hiện tên component được báo cáo kết thúc bằng `cd..`. Theo dõi cách tên đó trở thành một đường dẫn, sau đó xác minh rằng các tên không an toàn được xử lý mà không tạo ra một thư mục không thể phân giải; issue hoàn tất khi bản tái hiện tối thiểu không còn tạo ra đường dẫn có vấn đề.
