Performs a fused RoPE projection for Q and K with paged KV cache.

This is the paged equivalent of generic_fused_qk_rope_bshd_continuous_batch. It applies RoPE to both Q (returned) and K (in paged cache) to ensure proper dependency ordering after fused_qkv_padded_matmul.

Args:

q_proj (TileTensor): Query projection tensor of shape [batch, seq_len, n_heads, head_dim].
kv_collection (PagedKVCacheCollection): The paged KV cache collection.
freqs_cis (TileTensor): Frequency tensor for RoPE of shape [max_seq_len, head_dim].
layer_idx (UInt32): The layer index for accessing the correct cache.
valid_lengths (TileTensor): Tensor of shape [batch] containing the valid length for each sequence. RoPE is only applied to positions within these lengths.
output (TileTensor): Output tensor for Q with RoPE applied, same shape as q_proj.
context (DeviceContextPtr): Device context pointer for execution.
