A small linter that rejects noisy qualified Rust paths and blank lines between imports.
Run it from a Rust project directory:
```sh
jlint
```
A directory can be supplied explicitly:
```sh
jlint /path/to/project
```
Use `--no-banner` to suppress the startup message:
```sh
jlint --no-banner
```
The command exits with status 1 when disallowed paths or import spacing violations are found.
