Split platform into a portable core (mod.rs) plus unix.rs and windows.rs. - Linux: statx through syscall(2) so static musl links (fstatat fallback on ENOSYS); virtual-fs detection compares f_type as u32. - macOS: Finder trash (~/.Trash or /Volumes/X/.Trashes/<uid>, "name N" collisions, EXDEV falls through to the next location) and `open -R` reveal; never headless. - FreeBSD/NetBSD: fstatat with birth time; trash and reveal unsupported, permanent delete still available on headless systems. - Windows: std read_dir and metadata, allocated size unknown, no inode identity, Recycle Bin via SHFileOperationW (FOF_ALLOWUNDO, all architectures), Explorer /select reveal, no permanent delete, '\\' separator with Windows glob semantics, abs paths via GetFullPathNameW, config in %AppData%. - Local time via a portable LocalTime helper (localtime_r tm_gmtoff on Unix, SystemTimeToTzSpecificLocalTime on Windows) replacing libc tm and mktime in the TUI, snapshot and filter code. - errno, stat field names and mode_t width handled per OS; Unix-only tests gated; clippy clean on all targets. Adds windows-sys =0.61.2 (Windows only; Win32_Foundation, Win32_System_Time, Win32_UI_Shell), already in the lockfile via crossterm.
