Fixes the breaking CI for nodejs, related to the documentation of the
new Permutation API in typescript.
- Expanded the generated typings in `nodejs/lancedb/native.d.ts` to
include `SplitCalculatedOptions`, `splitNames` fields, and the
persist/options-based `splitCalculated` methods so the permutation
exports match the native API.
- The previous block comment block had an inconsistency.
`splitCalculated` takes an options object (`SplitCalculatedOptions`) in
our bindings, not a bare string. The previous example showed
`builder.splitCalculated("user_id % 3");`, which doesn’t match the
actual signature and would fail TS typecheck. I updated the comment to
`builder.splitCalculated({ calculation: "user_id % 3" });` so the
example is now correct.
- Updated the `splitCalculated` example in
`nodejs/lancedb/permutation.ts` to use the options object.
- Ran `npm docs` to ensure docs build correctly.
> [!NOTE]
> **Disclaimer**: I used GPT-5.1-Codex-Max to make these updates, but I
have read the code and run `npm run docs` to verify that they work and
are correct to the best of my knowledge.
