All 14 shadow-utils tools are now implemented.
groupadd: create groups with auto GID allocation, system groups, force mode.
groupdel: delete groups, checks for primary group usage.
groupmod: modify GID, rename, password changes.
grpck: verify /etc/group and /etc/gshadow integrity.
chfn: change GECOS sub-fields (name, room, phone).
chsh: change login shell with /etc/shells validation.
newgrp: change effective group with crypt(3) password verification.
449 tests, zero clippy warnings, all 14 tools in multicall binary.
Copilot findings (PR #36):
- parsers: use trim_start() for blank/comment detection, parse
untrimmed line to preserve GECOS whitespace
- pam: newline after password prompt is best-effort (let _ =)
New tests (#37):
- test_concurrent_lock_operations: 4 threads racing lock/unlock
- test_gnu_compat_status_output: compare -S output with GNU passwd
- test_gnu_compat_lock_unlock: verify lock/unlock matches GNU behavior
147 tests, zero clippy warnings.
