* @brief Applies a unary operation to a ggml tensor using the CANN backend.
*
* @details This function performs a unary operation on the input tensor using
* a user-provided lambda or callable object `unary_op`, which accepts the CANN
* context and two ACL tensors (source and destination). Internally, this function
* creates ACL representations of the ggml tensors and invokes the unary operation.
* The result is stored in the destination tensor `dst`. This utility abstracts the
* common boilerplate of tensor conversion and cleanup when implementing unary ops.
* @details This function applies a unary operation to the input tensor using
* a user-provided lambda or callable `unary_op`. The lambda receives the
* CANN backend context and two ACL tensors: the source and the destination.
*
* @param unary_op A callable that performs the unary operation using CANN APIs.
* @param ctx The CANN context used for operations.
* @param dst The destination tensor where the result will be stored.
* The source tensor is retrieved from `dst->src[0]`.
* Internally, this function handles the conversion from GGML tensors to ACL tensors,
* calls the provided unary op, and manages resource cleanup. The input is assumed
* to be `dst->src[0]`, and the result is written to `dst`.
*
* This utility simplifies writing unary op wrappers by abstracting tensor preparation.
*
* @param unary_op A callable that performs the unary operation using CANN ACL APIs.
* @param ctx The CANN context for operation execution.

* @brief Helper macro to invoke a unary ACL operation using ggml_cann_unary_op.
* @brief Applies a gated (GLU-style) unary operation using the CANN backend.
*
* This macro defines an inline lambda wrapping a specific ACL operation name,
* and passes it to the templated ggml_cann_unary_op function. It simplifies
* calling unary ops by hiding the lambda boilerplate.
* @details This function performs a gated activation such as GEGLU or ReGLU.
* It supports two input modes:
*
* 1. **Dual input mode**: `dst->src[0]` and `dst->src[1]` are both valid tensors.
* These are used directly as the value and gate tensors.
*
* 2. **Packed input mode**: Only `dst->src[0]` is valid, and it is assumed to
* contain a concatenation of value and gate along the first dimension. This tensor
* will be split into two equal halves to form the value and gate inputs.
*
* The function applies a user-provided unary operation (e.g., GELU) to the value tensor,
* then multiplies the result in-place with the gate tensor:
*
* Internally, the lambda will call:
* @code
* GGML_CANN_CALL_ACLNN_OP(ctx, OP_NAME, acl_src, acl_dst);
* dst = unary_op(value) * gate;
* @endcode
*
* The `swapped` parameter (from `dst->op_params[1]`) allows flipping the
* order of value/gate in the packed input case.
*
* @param unary_op A callable that performs the unary operation using CANN ACL APIs.
* It receives (ctx, acl_value_tensor, acl_output_tensor).
* @param ctx The CANN context used for execution.
* @param dst The destination ggml_tensor. Source tensors are in `dst->src[0]` and optionally `src[1]`.
