Address review feedback: gpu_ids and total_gpu_num select one binding method, per the vendor sgpu_km documentation. Do not describe a precedence between them; tell users to set exactly one parameter. Signed-off-by: wjluo <wjluo@ccoe.vip>
Add i18n/zh translation of how-to-use-mthreads-s5000.md and sync the five mthreads-device userguide pages with their English updates: card specification table, valid sgpu-memory values per model, memoryPerCard override for S5000, exclusive-allocation fill behavior, and the S5000 slice example.

| HAMi models each Mthreads card with a per-card memory capacity. The default of 96 units matches the MTT S4000 (48 GiB). The MTT S5000 has 80 GiB, so set `memoryPerCard` to `[160]`. Without this, exclusive allocations only get 48 GiB and larger slices (for example 128 units) are rejected. This parameter is cluster-level; clusters mixing S4000 and S5000 need separate node pools per card model. |

… upgrade path Signed-off-by: wjluo <wjluo@ccoe.vip>
- Use the correct chart value mthreadsMemoryPerCard (scalar) instead of the non-existent devices.mthreads.memoryPerCard list; the per-card memory is a single value, so mixed S4000/S5000 fleets need separate node pools. - Include the kubeScheduler image tag in the S5000 values file so the alternative install path does not drop it. - Replace marketing phrasing, clarify overcommit_ratio units (ClusterConfig ratio vs /proc percent), add expected output to verify commands, use a runnable MUSA image, and describe exclusive allocation as derived from the node-reported per-card capacity. - Move the S5000 guide out of the cloud-platform sidebar group.

Align the example with the documented resource pools.
The guide says that cards bound to sgpu_km enter the slice pool and that only unbound cards remain in the whole-card pool. With all eight cards bound, the example must not describe mthreads.com/gpu: 8 as eight whole cards. Correct the output to match the operator's actual representation, or leave cards unbound so that the whole-card count is valid.

The chart value devices.mthreads.memoryPerCard is a list (one entry per card model); a mixed MTT S4000/S5000 fleet is expressed as [96,160] and needs no separate node pools. This aligns the prose with the list-form revert in 4e0f357. Signed-off-by: wjluo <wjluo@ccoe.vip>

What this PR does / why we need it:
Documents running HAMi with Mthreads MTT S5000 (80 GiB) GPUs.
Add docs/installation/how-to-use-mthreads-s5000.md and register it in sidebars.js (Install > HAMi):
Install the Mthreads GPU Operator in Full mode with sGPU enabled, including by-card binding of the sgpu_km module (total_gpu_num vs gpu_ids, mutually exclusive)
Disable the vendor sGPU scheduling engine (gpuScheduler/gpuWebhook via ClusterPolicy, with the required mt-controller-manager restart)
Install HAMi via Helm with devices.mthreads.memoryPerCard: [160] (S5000 = 80 GiB = 160 x 512 MiB units; chart default 96 targets the S4000). Note: this value requires a HAMi release including the mthreads per-card memory feature (Project-HAMi/HAMi#2988), merged after v2.10.0; on v2.10.0 and earlier it is silently ignored.
sGPU host configuration (/proc/sgpu_km knobs), Mthreads device plugin reporting via node labels instead of annotations, and usage/slicing rules
Update docs/userguide/mthreads-device/ guides and examples for S5000: card specification table, valid sgpu-memory values per model (S5000: up to 160 incl. 128/160), a 64 GiB S5000 slice example, and exclusive-allocation fill behavior
