StreamTasks gRPC support

The Lattice SDK now supports streaming task updates in real-time using the gRPC API:

• Added StreamTasks gRPC endpoint for establishing persistent connections to stream task events
• Implemented Go/gRPC example demonstrating how to connect and process task streams
• Updated documentation to include gRPC usage patterns alongside existing REST examples

Key features

The StreamTasks gRPC API provides the same configurable parameters as the REST version:

• heartbeatIntervalMs: Configures how frequently the server sends heartbeat events to verify connection health.
• excludePreexistingTasks: Controls whether to stream only new tasks created after the connection is established or include existing tasks.
• taskType: Allows filtering the stream by task type prefix, reducing bandwidth usage and focusing on relevant task updates.

Documentation updates

As a part of this release, the Operate on tasks guide has been updated with a Go/gRPC code example. The example demonstrates how to establish a task stream connection, process heartbeat events, and handle incoming task events using the gRPC protocol.
