Add IPC messages and server-side implementation for streaming animated image decode. Instead of decoding all frames upfront, only decode an initial batch and keep the decoder alive for on-demand frame requests. New IPC messages: - request_animation_frames: request decode of a batch of frames - stop_animation_decode: clean up a decode session - did_decode_animation_frames: deliver decoded frames to client - did_fail_animation_decode: report decode errors The existing did_decode_image message gains a session_id parameter (0 for single-shot decode, non-zero for streaming sessions).
