fix(test-fixtures): lint/format/mypy + regen landing golden

- ruff format cache.py; drop a now-redundant local `from typing import Any`.
- Annotate the projection fixture's `full` dict as `dict[str, list[Any]]` so
  `RecordBatch.from_pydict` type-checks (was inferred `dict[str, object]`).
- Regenerate tests/landing/describe.expected.json for the 4 new
  cache_partition_* example functions (landing-conformance drift guard).
