[Windows] CLI crashes immediately: EUNKNOWN open 'B:\~BUN\locales\en_US.json' #8

Description

I installed the mammouth CLI on Windows following the official documentation.
When trying to run the command mammouth or even mammouth --version, the process crashes immediately with an EUNKNOWN error pointing to a non-existent path (B:~BUN...).

It seems like the localization files (y18n/yargs) are not correctly bundled in the Windows executable (Bun build).

Steps to reproduce

1. Install Mammouth on Windows (via PowerShell / Installation Script).
2. Open PowerShell.
3. Run mammouth or mammouth --version.
