LanceDB Robot bc8674ab22 chore!: update lance dependency to v9.0.0-rc.1 (#3673)
BREAKING CHANGE: splits generated by the permutation data loader will
not be the same, due to a change in hash function.

Updates the Lance dependencies and Java lance-core to
[v9.0.0-rc.1](https://github.com/lance-format/lance/releases/tag/v9.0.0-rc.1).
Includes the required DataFusion 54 and Lance file-reader compatibility
updates.

LanceDB Java Enterprise Client

Configuration and Initialization

LanceDB Cloud

For LanceDB Cloud, use the simplified builder API:

import com.lancedb.LanceDbNamespaceClientBuilder;
import org.lance.namespace.LanceNamespace;

// If your DB url is db://example-db, then your database here is example-db
LanceNamespace namespaceClient = LanceDbNamespaceClientBuilder.newBuilder()
    .apiKey("your_lancedb_cloud_api_key")
    .database("your_database_name")
    .build();

LanceDB Enterprise

For Enterprise deployments, use your custom endpoint:

LanceNamespace namespaceClient = LanceDbNamespaceClientBuilder.newBuilder()
    .apiKey("your_lancedb_enterprise_api_key")
    .database("your_database_name")
    .endpoint("<your_enterprise_endpoint>")
    .build();

Development

Build:

./mvnw install -pl lancedb-core -am
