TTY-Safe Process Utilities (src/lib.rs)

Utilities that detach subprocesses from a controlling TTY, reset OOM scores, and kill children when the parent dies. Reuse when a raw-mode TUI spawns git, npm, pagers, or other tools.

//! Lightweight process-spawning utilities for TTY safety.
//!
//! When a TUI/pager/raw-mode terminal owns the parent process's controlling
//! TTY, every child process must be detached — otherwise it (or its
//! grandchildren: npm, git, pinentry, ssh-agent …) can open `/dev/tty`
//! directly and spew mouse escape codes, capability-probe replies, or
//! credential prompts onto the live screen.
//!
//! This crate provides the minimal surface needed to make subprocess spawning
//! safe. It is intentionally tiny so that **every** crate in the workspace
//! can depend on it without pulling in heavyweight libraries.
