fix(cnn_v3): fix texture format mismatches in cnn_v3_test sequence

- seq_compiler: add gbuf_albedo/gbuf_rgba32uint to NODE_TYPES
- timeline: declare gbuf_feat0/feat1 as gbuf_rgba32uint, route
  CNNv3Effect output through cnn_v3_out (gbuf_albedo) + Passthrough
  to sink (dec0 can't write directly to Rgba8Unorm sink)
- cnn_v3_effect: fix update_bind_groups using .set() instead of
  .replace() causing FATAL assert on second frame
- TODO: add CNN v3 "2D mode" (G-buffer-free) future task

handoff(Gemini): CNNv3Effect now runs without crashes at --seek 48
