This change introduces `_add_events_to_memory_via_ingest` in `VertexAiMemoryBankService` to support adding events to memory using the `memories.ingest_events` API. This allows passing additional configurations such as `stream_id`, `force_flush`, and `generation_trigger_config`. This path is triggered when `custom_metadata` contains `use_ingest` or `generation_trigger_config`. Co-authored-by: George Weale <gweale@google.com> PiperOrigin-RevId: 900924805
