twislaandClaude Opus 5.5 a0e3868934 Debug Console put: verify the card's copy, never zero-fill after a failed write ...

Found by M3's shared-bus test: when the card refused a write, the retry
closed the file (losing up to 3 KB of earlier chunks still in the write
buffer), then truncate() extended it back with zeros. The checksum only
covered the received bytes, so `put` reported success with 3 KB of zeros
on the card. Now a retry gives up if the card lost data, and the finished
file is read back and must hash the same before it's renamed.

The card refuses a write about once in five 1.7 MB uploads, with the
radio asleep as often as listening.
