Describe the bug

pingora-core fails to compile on FreeBSD due to an outdated dependency.

Pingora info

Pingora version: 9ac75d0
Rust version: cargo 1.93.0 (083ac5135 2025-12-15)
Operating system version: FreeBSD 14.3-RELEASE

Additional context

pingora-core depends on an old version of the nix crate (0.24.3), which is causing the problem.
Updating the nix dependency to the latest version resolves the issue:

I’d be glad to submit a pull request with this change if desired.
