osobhandClaude Opus 5.5 989335b67b fix(format): bound a Blosc2 frame's offsets chunk by the HDF5 chunk size ...

parse_frame sized the offsets chunk from the frame header's own nbytes and
chunksize, so a 173-byte frame declaring 32 Mi chunks, with a 40-byte
repeated-value offsets chunk, built 256 MiB (up to 2 GiB) of offsets for a
1 MiB HDF5 chunk and then returned 4 bytes. The offsets chunk is now capped
at the output limit (at least 128 bytes); a frame whose nbytes/chunksize
imply more chunks than that is refused before anything is allocated.

tests/blosc2_alloc_bounds.rs measures peak allocation with a counting
global allocator; the reviewer's frame failed it (decoded Ok(4)) before.
