Crate whyno_gather 

Os-level state gathering for permission debugging.

Handles all system interaction: stat(), getxattr(), ioctl(FS_IOC_GETFLAGS), statvfs(), /proc parsing, and /etc/passwd + /etc/group resolution. gathered data is packaged Into whyno_core::state::SystemState for the check pipeline.

Mount flags (ro, noexec, nosuid) come from statvfs() — one Syscall, no text parsing. /proc/self/mountinfo is retained for Metadata only (fs_type, mountpoint, device).
