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)

Omar SobhandClaude Sonnet 4.6 90bdd7cd13 feat: add h5bench-equivalent Criterion benchmarks to clawhdf5-bench
Adds three Criterion benchmark suites mirroring the h5bench HPC I/O
benchmark workloads in pure Rust — no C libhdf5 required for the default
path, with an optional `libhdf5-compare` feature for side-by-side numbers.

  - benches/h5bench_write.rs: write_1d_contiguous, write_2d_chunked,
    write_f64_batch, write_multi_dataset, write_with_attrs
  - benches/h5bench_read.rs: read_sequential, read_f64_sequential,
    read_chunked_2d, read_from_disk, read_hyperslab
  - benches/h5bench_meta.rs: metadata_attrs_write, metadata_attrs_read,
    metadata_groups_create, metadata_groups_traverse, metadata_string_attrs

All benchmarks pass `cargo bench --bench <name> -- --test` and clippy
reports zero warnings.  Run with `cargo bench -p clawhdf5-bench`.
