- Introduced Lab 17 documentation detailing the installation of HAMi DRA 0.2.3 and the Ascend DRA driver on an Ascend 310P3 node. - Updated the overview and sidebar to include Lab 17, highlighting its focus on request-to-ResourceClaim conversion, two-Pod NPU sharing, memory quota enforcement, and scheduler capacity accounting. - Enhanced the tutorials overview to reflect the addition of Lab 17 and its objectives. Signed-off-by: Jimmy Song <jimmy@dynamia.ai>
Renumber the Ascend HAMi DRA lab to Lab 18 (master added a KitOps Lab 17) and register the KitOps zh tags.
Lab 18 is taken upstream by hami-linkerd-noisy-neighbor, so the Ascend NPU Sharing lab becomes Lab 19 across tutorials, overview, and the companion blog post (en + zh). Adds blog diagrams. Signed-off-by: Jimmy Song <jimmy@dynamia.ai>
Resolve conflicts keeping both lab entries: linkerd Lab 18 first, ascend-hami-dra Lab 19 second (sidebar), and kitops/modelkit plus service-mesh tags (zh tags.yml). Add missing Lab 18 overview entries (en + zh) that upstream skipped. Signed-off-by: Jimmy Song <jimmy@dynamia.ai>

| In soft-slicing mode both containers see the same `/dev/davinci0`, not two vNPU device nodes; the isolation is done by libvnpu in user space. After a real workload runs in Step 8, the node's `npu-smi` process list shows both containers' processes on NPU 4. | ||
