[Bug (iota-move)]: iota move new fails if using only the required argument <NAME> with uppercase letter(s)

[roman1e2f5p8s]

Bug description

Creating a new Move package with the iota move new command using only the required argument <NAME> fails with No such file or directory (os error 2) if <NAME> contains uppercase letter(s).

Rust version

rustc 1.83.0 (90b35a623 2024-11-26)

Version

develop branch

Steps To reproduce the bug

cargo build
./target/debug/iota move new Xxx

Expected behaviour

$ ./target/debug/iota move new Xxx
$ tree Xxx
Xxx
├── Move.toml
├── sources
│   └── xxx.move
└── tests
    └── xxx_tests.move

3 directories, 3 files

Actual behaviour

$ cargo build
$ ./target/debug/iota move new Xxx
No such file or directory (os error 2)

That is, ./target/debug/iota move new Xxx fails with the following error: No such file or directory (os error 2).

2. While folder Xxx is created, its content is incomplete: Xxx/sources is empty, Xxx/tests is not created at all:

$ tree Xxx
Xxx
├── Move.toml
└── sources

2 directories, 1 file

3. Note that if ./target/debug/iota move new Xxx is executed after ./target/debug/iota move new xxx, the former command will not fail. However, ./target/debug/iota move new Xxx will write some contents into xxx instead of Xxx:

$ ./target/debug/iota move new xxx
$ ./target/debug/iota move new Xxx
$ tree xxx
xxx
├── Move.toml
├── sources
│   └── xxx.move
└── tests
    └── xxx_tests.move

3 directories, 3 files
$ tree Xxx
Xxx
├── Move.toml
└── sources

2 directories, 1 file

Errors

- No such file or directory (os error 2)
