fix: gzip crash-safety + size rotation always bounds live file (logsetup-7/8/9)

_gzip_file now writes to a .tmp sibling and atomically os.replaces it onto
the final .gz path, so a crash/OOM mid-write can never leave a truncated
.gz where retention trusts it; retier's plain/gz dedupe additionally
verifies a .gz decompresses cleanly before removing its plain twin, so a
corrupt .gz is never preferred over the last intact copy.

rotate="size" now always forces the handler's backupCount to fire
regardless of backup_count, so backup_count=0 means "keep zero rolled
files" (each roll deletes itself immediately) instead of silently
disabling rotation and growing the live file unbounded.

Also mirrors retier's mtime+roll-counter sort key into prune() so a
same-second burst with tied mtimes prunes the oldest files instead of
arbitrary listdir order (logsetup-9, adjacent one-line fix).

Bumps to v0.5.1.
