Great to see more Rust-based tooling coming to FreeBSD. Regarding the architecture, how are you handling Job Control and signal propagation? Specifically, are you using a custom wrapper for libc to manage tcsetpgrp and foreground process groups, or are you leveraging a specific Rust crate for asynchronous signal handling? I’m curious to see how GRSH maintains the 'native' feel when managing complex pipelines on the FreeBSD kernel.
