fix: complete imagecodecs codec package hints

[d-v-b]

🤖 AI text below 🤖

Missing Zarr v3 imagecodecs such as imagecodecs_lzma, imagecodecs_avif, and imagecodecs_jpegls currently give no package hint, despite being registered by imagecodecs-zarr. Add all 81 exact names from its published 2026.8.16 wheel: 68 newly recognized names and 13 existing names that now list both imagecodecs-zarr and virtual-tiff. Preserve the virtual-tiff-only jpeg8 and jetraw entries.

The table cites the provider release. Update the regression tests to exercise missing-codec errors for newly recognized names, shared providers, legacy providers, and an unknown imagecodec name. Add a changelog entry.

Validation:

• Registry and configuration suites: 87 passed in the Hatch Python 3.12 minimal environment.
• Compared the complete imagecodecs-zarr mapping against zarr.codecs in the published wheel: exactly 81 names, with no missing or extra entries.
• Ruff lint and formatting checks passed.
• Repository pre-commit checks passed, including mypy, codespell, and numpydoc validation.
