Omar SobhandClaude Sonnet 4.6 e82b8f56bd bench: enable zstd in bench crate, update codec comparison results
Add features = ["zstd"] to clawhdf5-bench dev-dependency so the
write_2d_chunked_zstd benchmark no longer panics with UnsupportedFilter(32015).

Update BENCHMARKS.md and README.md with measured results from the full
h5bench write suite (2026-06-30, post write-performance improvements):
- Zstd-3 hits 593 MiB/s at 512×512 vs deflate-6's 280 MiB/s (2.12×)
- Zstd-3 hits 330 MiB/s at 128×128 vs deflate-6's 132 MiB/s (2.51×)
- Sequential f64 batch write improved ~8-11% from owned-Vec IO path

Omar SobhandClaude Sonnet 4.6 bf197b70e3 docs+fix: add h5bench benchmark results and repair libhdf5-compare feature
Add h5bench-equivalent Criterion benchmark results to BENCHMARKS.md
(sequential read/write, chunked read/write, metadata throughput).

Fix libhdf5-compare feature for HDF5 1.14.x:
- Switch to hdf5-metno 0.12 (aliased as 'hdf5') in clawhdf5-bench
- Fix h5bench_meta.rs: AttributeBuilderEmpty::create takes &str not &String;
  shape=[1] dataset uses write(&[val]) not write_scalar
- Fix h5bench_read.rs: libhdf5-compare variant now writes its own reference
  file via hdf5-metno instead of dumping clawhdf5 bytes (avoids float
  datatype message incompatibility)
