The `add_memory` methods in `Context` and `BaseMemoryService` now accept `MemoryEntry` objects in addition to strings. The Vertex AI Memory Bank service implementation is updated to handle these new types

add_events_to_memory now supports memory_write_mode to select generate (event-based extraction/consolidation) or create (direct raw fact writes via memory_facts). This now lets custom memory pipelines while keeping generate as the default path

Adds BaseMemoryService.add_events_to_memory(session, events=..., custom_metadata=...) and CallbackContext.add_events_to_memory(events=..., custom_metadata=...) so callers can add memories from an explicit subset of ADK events.

This change introduces an add_session_to_memory method to both CallbackContext and ToolContext, allowing agents and tools to explicitly trigger the saving of the current session to the memory service. This enables more fine-grained control over when session data is persisted for memory generation. A ValueError is raised if the memory service is not configured.

Enhanced `save_artifact` in `callback_context.py` to accept `custom_metadata` and added `get_artifact_version` to retrieve artifact details.
Introduced a new sample, `context_offloading_with_artifact`, demonstrating how to use ADK artifacts to offload large data from the LLM context. The sample includes:
- `QueryLargeDataTool`: Generates mock sales reports, saves them as artifacts with custom metadata, and injects the artifact content into the LLM request immediately after creation.
- `CustomLoadArtifactsTool`: Provides summaries of available artifacts to the LLM based on metadata and loads artifact content on demand when `load_artifacts` is called.
