v0.2.0 — uutils adoption

First release under the uutils organization.

Highlights

• Repo transferred from shadow-utils-rs/shadow-rs to uutils/shadow-rs
• uucore 0.8 — aligned with latest uutils ecosystem
• nix → rustix — full migration, raw syscalls without libc overhead
• Standalone per-tool install — make install now installs 14 individual binaries with least-privilege setuid layout matching GNU shadow-utils (#138)
• Non-panicking I/O — all println!/eprintln! replaced with graceful writes (#141)
• Unwind tables suppressed — no binary layout leakage from setuid-root tools (#143)
• NSS-backed user lookup — getpwuid_r for LDAP/SSSD/systemd-homed compatibility (#147)
• 35+ security findings addressed across 6 review rounds (Copilot + Gemini)
