chore(release): v2.2.0, point repository URLs at git.redclaw.dev

Bump all workspace crates, the node package and pyproject to 2.2.0 and
finalize the changelog. The repository URL in every manifest pointed at a
GitHub location that does not resolve; use the real origin.

   reading compound types and — critically — every chunked/compressed dataset
   written by HDF5 2.0. Found by running the h5py interop tests against
   h5py 3.16 / HDF5 2.0.
+  Independently reported (with a patch) against the v2.1.0 tag by
+  M. Scot Breitenfeld (The HDF Group) — v2.1.0 predates this fix.
+- `clawhdf5-format`: parse HDF5 2.0 native complex datatypes (class 11,
+  datatype version 5, e.g. `H5T_COMPLEX_IEEE_F64LE`). The properties are a
+  single base floating-point datatype, not a compound-style member list; the
+  old parser read the base type's bytes as member names, producing a garbage
+  datatype, and failed with `UnexpectedEof` when a complex type was nested in
+  a compound. It is now surfaced as the equivalent `{r, i}` compound (the
+  shape h5py writes for numpy complex dtypes), with a size check against the
+  base type. Validated end-to-end against an HDF5 2.0-written file.
 
 ### Performance

+
+## Compound datatype message version 5 is not parsed (HDF5 2.0)
+
+**Status:** fixed on `main` in `a13ff51` (2026-06-03); **not in the v2.1.0
+tag**, which was cut five commits earlier. Ships in the next release.
+
+**Reported by:** M. Scot Breitenfeld (The HDF Group), 2026-09-08, against v2.1.0.
+
+**Summary:** `clawhdf5-format` v2.1.0 rejects any dataset with a compound
+(struct) datatype written by an HDF5 2.0 library in `libver='latest'` mode:
+`InvalidDatatypeVersion { class: 6, version: 5 }`.
+
+**Reproduction** (h5py 3.16.0 / HDF5 2.0.0):
+
+```python
+import h5py, numpy as np
+dt = np.dtype([('x', 'f8'), ('y', 'f8'), ('id', 'i4')])
+data = np.array([(1.0, 2.0, 10), (3.0, 4.0, 20)], dtype=dt)
+f = h5py.File('compound.h5', 'w', libver='latest')
+f.create_dataset('particles', data=data)
+f.close()
+```
+
+Committed as `crates/clawhdf5-format/tests/writer_h5py_tests.rs::read_h5py_generated_compound`
+(`#[ignore]`d; needs `python3` with h5py on `PATH`). Run with
+`cargo test -p clawhdf5-format --test writer_h5py_tests -- --include-ignored`:
+v2.1.0 gives 25 passed / 1 failed; `main` passes everything.
+
+**Root cause:** the compound (class 6) branch of `Datatype::parse`
+(`crates/clawhdf5-format/src/datatype.rs`) accepted only versions 1–4. Datatype
+message versions 4 and 5 changed only the Reference and Complex classes, so a
+v5-tagged compound uses the unchanged v3 member-list layout.
+
+**Fix:** versions 3–5 are accepted for compound (class 6) and array (class 10)
+datatypes, and data layout message version 5 is accepted too (needed for every
+chunked dataset written by HDF5 2.0). Byte-level regression tests:
+`test_compound_v5_from_hdf5_2_0`, `test_array_v5_from_hdf5_2_0`.
+
+## Native complex datatype (class 11) is mis-parsed (HDF5 2.0)
+
+**Status:** fixed 2026-09-18. Found while validating the report above.
+
+**Summary:** HDF5 2.0 native complex types (`H5T_COMPLEX_IEEE_F64LE` etc.)
+were parsed as if they carried a compound-style member list. The properties are
+actually a single base floating-point datatype, so the parser produced a garbage
+datatype, or `UnexpectedEof` when the complex type was a compound member. h5py's
+default numpy-complex mapping is unaffected (it writes a `{r, i}` compound);
+only files using the native type through the C API / h5py low-level API hit this.
+
+**Fix:** class 11 parses its base type and is surfaced as the equivalent
+`{r, i}` compound. Tests: `test_complex_v5_from_hdf5_2_0`,
+`test_compound_with_complex_member_from_hdf5_2_0`,
+`writer_h5py_tests.rs::read_h5py_generated_native_complex`.
+
+## Revised reference datatype (class 7, version 4) is not parsed
+
+**Status:** open, unconfirmed against a real file.
+
+**Summary:** HDF5 1.12+ `H5T_STD_REF` references use datatype version 4 with
+reference types 2–4 (object2 / region2 / attribute), which `Datatype::parse`
+rejects with `InvalidReferenceType`. h5py still writes the legacy v1
+object/region references, which read correctly, so no reproducing file has been
+generated yet; one written with the C API (`H5T_STD_REF`) is needed.
+
+## `clawhdf5-gpu` `gpu_tests` can hang under the default parallel test runner
+
+**Status:** open. Observed 2026-09-18 (RTX 5060 Ti, Linux).
+
+**Summary:** during `cargo test --workspace`, the `gpu_tests` binary sat idle
+(~1% CPU) for 25+ minutes and had to be killed. Run single-threaded it passes
+in seconds (20/20): `cargo test -p clawhdf5-gpu --test gpu_tests -- --test-threads=1`.
+Suspected cause: several tests creating wgpu devices concurrently (possibly
+compounded by the rest of the workspace's tests loading the machine). Not yet
+root-caused; workaround is `--test-threads=1` for that crate.
