### What this PR does / why we need it?
Issue: If a model such as Ling-1T adopts partial rotary position
embedding (partial RoPE), but config.json uses the rotary_dim parameter
instead of partial_rotary_factor, it will trigger a RuntimeError: The
expanded size of the tensor (128) must match the existing size (64) at
non-singleton dimension 3.

This PR addresses an issue where models using partial rotary position
embedding (partial RoPE) with the `rotary_dim` parameter in
`config.json` (instead of `partial_rotary_factor`) would encounter a
`RuntimeError`.
This change adds support for the `rotary_dim` parameter in
`vllm_ascend/ops/rotary_embedding.py` to correctly calculate the
`rope_dim`, resolving the tensor size mismatch error.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
The patch was tested successfully with the Ling-1T model, which
previously triggered the error.

### What this PR does / why we need it?
This PR fixes a bug in the `test_triton_fusion_ops` test case. The test
compares a fused kernel (`fused_sigmoid_gating_delta_rule_update`) with
a split implementation. Both paths use a recurrent state tensor.
The bug was that the state tensor was being modified in-place by the
fused kernel call, and this modified tensor was then reused for the
split implementation path. This led to an incorrect comparison and test
failure.
This fix ensures that each path starts with an identical, clean initial
state by creating separate tensors. It also changes the state
initialization from `torch.randn` to `torch.ones` to make the test
deterministic.
### Does this PR introduce _any_ user-facing change?
No, this change only affects a test case and has no user-facing impact.
### How was this patch tested?
The fix is applied directly to the test case. The CI passing for
`test_fused_sigmoid_gating_delta_rule.py` will confirm that the fix is
working as expected.

### What this PR does / why we need it?
This PR focuses on performance optimization for the DispatchFFNCombine
operator. The key optimizations include:
1. Improving communication efficiency by merging the transmission of
tokens and scales;
2. Decoupling multi-core dependencies and reducing waiting bubbles in
the combine process through tile-granularity communication;
3. Optimizing the full-card synchronization overhead before the
umpermute operation.
These optimizations aim to reduce the overall execution latency of the
DispatchFFNCombine operator and enhance the runtime performance of the
model inference process on Ascend devices.
### Does this PR introduce _any_ user-facing change?
No. This PR only involves internal performance optimization of the
DispatchFFNCombine operator and does not introduce any changes to
user-facing APIs, interfaces, or behaviors.
### How was this patch tested?
1. Enable the DispatchFFNCombine operator by setting the environment
variable:
```
export VLLM_ASCEND_ENABLE_FUSED_MC2=1
```
2. Run the standard model inference test suite with the above
environment variable enabled;
4. Verify the correctness of model outputs (ensuring no functional
regression) and measure the performance improvement of the
DispatchFFNCombine operator (reduced latency and improved throughput).

### What this PR does / why we need it?
This PR removes the custom `rotary_embedding` operator and its
associated C++ kernel implementation, PyTorch bindings, and tests.
The codebase now falls back to using the native
`torch_npu._npu_rotary_embedding` implementation. This change simplifies
the codebase by removing custom, platform-specific kernel code and
relying on the standard NPU library implementation, which is presumably
more optimized and easier to maintain.
### Does this PR introduce _any_ user-facing change?
No. This is an internal refactoring and does not introduce any
user-facing changes.
### How was this patch tested?
The tests for the custom `rotary_embedding` operator have been removed
along with the operator itself. The correctness of the fallback to the
native `torch_npu` implementation is verified by existing CI tests for
attention layers and models that use rotary embeddings.

### What this PR does / why we need it?
This PR fixes an accuracy issue that occurs when using Prefill/Decode
Context Parallelism (PCP/DCP) in conjunction with speculative decoding
(MTP). The issue is caused by an irregular attention mask shape when
both features are enabled.
The fix involves flattening the `block_table` for speculative decoding
requests under PCP/DCP to ensure a regular attention mask. This PR also
introduces a `use_cp` property for cleaner code and updates dummy runs
to handle this scenario correctly.
### Does this PR introduce _any_ user-facing change?
No. This is a bug fix that improves accuracy and should not have
user-facing API changes.

### What this PR does / why we need it?
**Optimization:** Replaces fixed block sizes (128x128x128) in
`linear_persistent_kernel` with adaptive selection logic that considers:
- Matrix dimensions (M, N, K)
- Device NPU vector core count
- Data type (float32 vs others)
**Why:** Fixed block sizes lead to suboptimal hardware utilization
across different matrix shapes. Adaptive sizing maximizes occupancy and
memory efficiency for varied workload patterns, improving throughput for
batch-invariant linear operations in LLM inference.
**Details:**
- Small matrices (M < 256): Size-proportional allocation
- Medium matrices (256 ≤ M < 1024): Balanced distribution based on grid
capacity
- Large matrices (M ≥ 1024): Optimized for dominant dimension
### Does this PR introduce _any_ user-facing change?
No. This is a performance optimization. The API and numerical results
remain unchanged; only kernel execution efficiency improves.

### What this PR does / why we need it?
This PR reverts "[ModelRunner] Revert [Fix] Pads query_start_loc to
satisfy FIA/TND constraint #6459 (commit
5b0a6bcfe9)" and fixes a check in
`model_runner_v1`.
**A key change is that we remove the strict assertion in the latest
commit, as it turns out MLA + PIECEWISE will slice during computing,
leaving our assertion uncalled for and will only cause false alarm.**
This handles both uniform and mixed batches (by inserting a dummy
request for mixed batches), consolidates ad-hoc padding into a single
helper, copies the updated buffer to the device, which prevents kernel
mismatches or failures and ensure correct shapes for FIA/TND execution
in full graph modes.
We currently place this helper in `execute_model`. My original design
was to include it in `_prepare_inputs`, but that doesn’t work because it
must run after padding. While I’d prefer to minimize the impact and
reuse as much of the base class as possible in the future, it doesn’t
seem achievable at the moment.

6 * layer_num data movement between L1 Cache and HBM for one request on
decode node. Usually, decode node uses graph mode, so these op kernels
will be called between decode forward launched by an async thread in
mooncacke connector, this kernels maybe last for several decode forward
and TTFT will increase by 3~4 decode forward time.
In this PR, we implement an AscendC fused op
`transpose_kv_cache_by_block` to do this with only once kernel launch
and move data between L1 Cache and HBM only once.
After using this fused op, the time cost in transpose kv cacke layout
can be decreased to 0.24ms from 7ms in UT on 910C, and in PD
disaggregation scenario, TTFT can decrease about 90 ~ 110 ms in
qwen3-235B.

### Does this PR introduce _any_ user-facing change?
Use fused op by default, incase the op has bug in any scenario, provide
fallback choice using env to disable it.
**DISABLE fused op by add following env**
`export VLLM_ASCEND_FUSION_OP_TRANSPOSE_KV_CACHE_BY_BLOCK=0`

### What this PR does / why we need it?
1. Disable the feature to exit early upon encountering an error in order
to complete all tests.
2. Within each partition, tests are re-sorted by `estimated_time` in
ascending order. This allows the CI to cover as many test cases as
possible in the early stages.
