ningsh7 ef11e44adc feat(node): expose allowExternalBlobOutsideBases in Table.add (#4317)
## Summary

- Add `allowExternalBlobOutsideBases` to the Node `AddDataOptions` and
forward it through N-API to the Rust `AddDataBuilder`.
- Document its default and local-only external blob behavior.
- Cover URI strings and URI objects, option scoping, progress callbacks,
overwrite mode, and remote rejection.

## Validation

- `pnpm test --runInBand` (21 suites passed, 1 skipped; 908 tests
passed, 6 skipped)
- `pnpm lint-ci`
- `pnpm tsc`
- `pnpm run docs`
- `cargo fmt --all -- --check`
- `CC=clang cargo clippy --profile ci -p lancedb-nodejs --all-features
-- -D warnings`

const db = await lancedb.connect("data/sample-lancedb");
const table = await db.createTable("my_table", [
  { id: 1, vector: [0.1, 1.0], item: "foo", price: 10.0 },
  { id: 2, vector: [3.9, 0.5], item: "bar", price: 20.0 },
]);
const results = await table.vectorSearch([0.1, 0.3]).limit(20).toArray();
console.log(results);
