Ikki NishiharaandClaude Sonnet 5.5 c34090f2d2 CFB: bound the DIFAT and FAT chain walks by the file's own size
The DIFAT guard came from the header's sector count and the chain guard from
the FAT length, both of which a file can inflate. A chain cannot have more
sectors than the file holds: bound both walks by that.
