dgraph4j v25.0.0

This is a major release of the Dgraph Java client, bringing full parity with the Dgraph v25 API. It adds new APIs for RunDQL, ID allocation, and namespace management, a typed exception hierarchy with automatic retry support, and convenience methods for common schema and data operations.

What's Changed

New APIs:

• RunDQL — run DQL queries and mutations directly without managing transactions
• ID Allocation — allocateUIDs(), allocateTimestamps(), allocateNamespaces()
• Namespace Management — createNamespace(), dropNamespace(), listNamespaces()
• Convenience Methods — dropAll(), dropData(), dropPredicate(), dropType(), setSchema()

All methods available on both DgraphAsyncClient (returning CompletableFuture<T>) and DgraphClient (sync wrapper).

Typed Exception Hierarchy:

All exceptions now extend DgraphException (which extends StatusRuntimeException), with isRetryable() on every subclass. Existing catch (StatusRuntimeException e) blocks continue to work.

Automatic Retry:

withRetry() on both DgraphClient and DgraphAsyncClient provides managed transaction retry with exponential backoff, configurable via RetryPolicy with support for read-only and best-effort transactions.

Other changes:

• Updated proto definitions to Dgraph v25 (8 new RPCs)
• Updated copyright from Hypermode Inc. to Istari Digital, Inc.
• Updated GitHub org references from hypermodeinc to dgraph-io
• Deprecated clientStubFromSlashEndpoint / clientStubFromCloudEndpoint (now throw UnsupportedOperationException with migration guidance)
• Fixed isJwtExpired() to handle UNKNOWN status code
• Added CD workflow to publish releases to Maven Central
