Add guard clauses to skip processing when the token/frame count is zero, preventing tensor dimension mismatches during KV cache expansion (e.g. 'expanded size (0) must match existing size'). Guards added in: - DenoiseBlock: skip denoising loop when num_frames == 0 - CleanKVCacheBlock: skip cache cleaning when num_frames == 0 - RecacheFramesBlock: skip recaching when num_recache_frames == 0 - causal_rope_apply: pass through when seq_len == 0 Fixes daydreamlive#500
