feat(api): Add shell call streaming events and image partial fields

[apcha-oai]

Summary

Add new shell-call streaming event models and ResponseStreamEvent accessors, add optional image partial metadata fields, and add a new audit-log event kind. Existing Responses WebSocket event types remain available; custom event Visitor implementations must handle the new shell-event cases.

Changes

• Keep structured chat-completion metadata accessors in sync and preserve missing-value handling through R8/ProGuard.
• Introduce new streaming event models for shell calls: ResponseShellCallCommandAddedEvent, ResponseShellCallCommandDeltaEvent, ResponseShellCallCommandDoneEvent, ResponseShellCallOutputContentDeltaEvent, ResponseShellCallOutputContentDoneEvent (and beta counterparts).
• Add ResponseStreamEvent factory/accessor methods for shell-call events (ofShellCallCommandAdded/Delta/Done and ofShellCallOutputContentDelta/Done) so stream events can be created and queried for these types.
• Add visitor methods in ResponseAccumulator to handle the new shell-call streaming event types so accumulated stream visitors can process them.
• Extend BetaResponseImageGenCallPartialImageEvent and ResponseImageGenCallPartialImageEvent with new optional fields background, output_format, quality, and size and expose typed getters for these fields.
• Add TENANT_ADS_ACCOUNT_ONBOARDING_REDEMPTION as a new audit log event kind in AuditLogListParams and AuditLogListResponse.

Two merge-blocking issues remain on this generated promotion:

1. The stable/beta stream and server Visitor interfaces gain five abstract methods. Existing source implementations stop compiling; old binaries can throw AbstractMethodError when a new shell event dispatches, rather than reaching the existing unknown fallback. Please change the generator to emit real JVM-default implementations for newly added cases through a common fallback, and add source plus precompiled-binary compatibility fixtures. Verify the generated bytecode contains default methods.

2. The direct FunctionShellCallOutputContent component ref is emitted as a second public nested Output/Outcome/Exit graph, creating new 1,183- and 1,386-line event files. Please fix the generator model-name/reference overlay so the event reuses ResponseFunctionShellCallOutputContent and its beta peer, regenerate the shared models with optional created_by, and avoid handwritten generated-file splitting.

   class Output

Low thermo follow-up: the generated union tests add an exhaustive negative-accessor matrix, growing stable 7,533→8,310 and beta 8,189→9,026 for five variants. Please move that invariant to a shared/parameterized generator template rather than continuing quadratic growth.
