Support for FreeBSD

### Description

Dear all,

I worked the last days on a port for FreeBSD so users can easily install vp using `pkg install vite-plus`.
I have a the ports building fine, but some patches needed to be applied.

Is the project open so I can create a pull request to get that patches included here upstream?

I yes I would prepare a pull request and would link it to this issue.

### Suggested solution

I will provide a pull request if patches for FreeBSD are welcome.
One patch goes into this repo

The second patch would be for:
https://github.com/voidzero-dev/vite-task/tree/main/crates/fspy
