fix: remove cmd.exe wrapper in run_binary to fix paths with spaces (#1280)

On Windows, when the executable path contains spaces (e.g. username
'John Doe'), cmd.exe /c strips quotes incorrectly causing the command
to fail with 'C:\Users\John' is not recognized as an internal or
external command.

This fix removes the unnecessary cmd.exe wrapper and calls the
executable directly via Command::new(), consistent with the pattern
used elsewhere in the codebase (system_ocr.rs, window.rs). The
CREATE_NO_WINDOW flag (0x08000000) is already set via creation_flags,
so the cmd.exe wrapper was redundant.

Closes #1279
