3f23ed7a11 minizip: place erase temp on same filesystem when TMPDIR differs 
minizip_erase rewrites the archive to a temp file under TMPDIR and
then renames it onto the source. rename(2) returns EXDEV across
filesystems, so when TMPDIR (e.g. /tmp) and the source live on
different mounts (a common conda-forge pattern), the rename fails
after the original was already moved aside to .bak — the next
operation that opens the archive sees no file and reports -111.

Add mz_os_path_same_fs() and have minizip_erase fall back on POSIX to
a same-dir temp when TMPDIR is on a different filesystem. POSIX uses
stat() st_dev comparison; Win32 uses _wstati64 for the parallel check
but the caller skips it under #ifndef _WIN32 because MoveFileExW with
MOVEFILE_COPY_ALLOWED already absorbs cross-volume rename internally.

Make the same-dir tmp filename unique (mz_ms_time suffix) and refuse
to clobber an existing leftover from a prior crash.

Refs #943.

21606891ab Support compression levels >= 10 and use zstd's internal default level. 
zstd supports regular compression levels 1 through 22.  The special
level 0 indicates to use zstd's internal default (currently level 3).
