Subject: [PATCH 01/14] fix: change CI suite from debug-full to full for
 optimization_debug_options tests

- test_npu_cuda_graph_bs.py: debug-full-2-npu-a3 -> full-2-npu-a3
- test_npu_embedding_interpolation.py: debug-full-1-npu-a3 -> full-1-npu-a3
- test_npu_no_extra_forked_npu_context.py: debug-full-2-npu-a3 -> full-2-npu-a3

Subject: [PATCH 03/14] chore: remove redundant debug stderr assertions in
 msprobe and cuda graph bs tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove debug print block in test_npu_cuda_graph_bs.py and stderr
assertions in test_npu_msprobe_dump_config.py — both are redundant;
the downstream assertions (assertEqual on decode_bs and dump.json
file check) already cover the end-to-end validation.

Subject: [PATCH 13/14] fix: Use column-based PID parsing in npu-smi output

Replace heuristic PID detection with explicit column-index lookup via
'Process id' header. Add psutil.pid_exists() cross-validation to prevent
misidentifying memory values (e.g. 4696, 1538) as PIDs.

Subject: [PATCH 14/14] fix: make TTFT comparison assertion meaningful

Replace two weak assertGreater(x, 0) with a real comparison:
max_bs=1 should have higher TTFT than max_bs=8 due to lack of batching.
