Possible mistranslation: "different TiDB nodes" in dev-guide-hybrid-oltp-and-olap-queries.md

1. What is the URL/path of the document related to this issue?

https://github.com/pingcap/docs/blob/master/develop/dev-guide-hybrid-oltp-and-olap-queries.md

The current English text (release-8.5/master) says:

Note that TiFlash and TiKV storage engines usually use different TiDB nodes, so the two query types are not affected by each other.

2. How would you like to improve it?

The corresponding Chinese source (docs-cn, same file) says:

需要指出的是，因为 tiflash 和 tikv 存储引擎通常属于不同的计算节点，所以两种查询类型互相之间不受影响。

"计算节点" is a generic term meaning "compute node(s)" — it does not refer to the TiDB (SQL layer) component specifically. TiFlash and TiKV are storage-layer components; they do not run on "TiDB nodes" architecturally, so the current English wording appears to be a mistranslation that introduces an inaccurate technical claim.

The sentence should say that TiFlash and TiKV usually run on different (compute) nodes — not "different TiDB nodes". Possible rewordings:

• "...TiFlash and TiKV storage engines usually use different nodes, so..."
• "...TiFlash and TiKV storage engines usually run on different compute nodes, so..."

Filing this as an issue rather than a PR since I'm not fully certain which exact wording best matches the intended meaning — happy to open a PR once the wording is confirmed.
