Chris LuandClaude Opus 5.5 6eb2fb4842 filer: stop full-chunk reads at the chunk size after a mount truncate (#12632 )

* util/http: stop a full-chunk read at the chunk's recorded size

weed mount shrinks a chunk's Size in place on ftruncate but leaves its
needle untouched. A view covering the whole shortened chunk is fetched
without a Range header, so the reader returned every stored byte. The
filer GET then wrote past the declared Content-Length and sent an empty
body, and the stream reader served the stale tail.

ReadUrlAsStream and the cipher path now deliver at most size bytes;
size 0 still reads the whole needle for manifest and log chunks.

* s3api: limit a plain chunk read to the requested size

A full-chunk read sends no Range header, so a chunk shortened by a mount
truncate streamed its whole needle into the S3 response.

* util/http: still report a failure past the chunk size

The volume server aborts a full-needle response when the needle fails
its checksum, and only at the end. Stopping at the chunk size missed
that, so a damaged copy read as healthy. Read the rest of the body and
return its error so the caller tries another copy.
