[OblivRuinDev]

Description

Add entry Automatic-Module-Name: ai.z.openapi.sdk in MANIFEST.MF to add support for Java 9+ module system
通过在文件MANIFEST.MF中添加条目Automatic-Module-Name: ai.z.openapi.sdk来向Java 9+模块系统添加支持

否则在Java 9+的模块化项目使用此SDK将造成各种模块找不到的错误

Should update version number and publish sdk to maven central?
You own write premission, can add new commits to patch-1 branch.
应该更新版本号并发布sdk到Maven Central吗
你拥有写权限，可以在当前分支(patch-1)上添加commit

Note that I don't know whether the Automic-Module-Name should be "ai.z.openapi" or "ai.z.openapi.sdk".
注意，我不确定模块名(Automic-Module-Name)应该为“ai.z.openapi”还是“ai.z.openapi.sdk”

Pull request overview

This PR adds Java 9+ module-system friendliness for the zai-sdk artifact by embedding a stable Automatic-Module-Name into the generated JAR manifest.

Changes:

• Add Automatic-Module-Name: ai.z.openapi.sdk to the JAR manifest for the core (zai-sdk) module via maven-jar-plugin.
• Add a note in the root pom.xml indicating that maven-jar-plugin changes should be kept in sync with core/pom.xml.

Reviewed changes

File	Description
pom.xml	Adds a reminder comment to keep jar-plugin configuration aligned with the core module.
core/pom.xml	Configures maven-jar-plugin to emit Automatic-Module-Name in the built SDK JAR manifest.

core/pom.xml:203

• core/pom.xml now duplicates the parent maven-jar-plugin configuration (Implementation-* manifest entries) just to add Automatic-Module-Name. This creates a drift risk (the parent pom even notes that changes should be kept in sync). Consider inheriting the parent jar-plugin config and only specifying the additional Automatic-Module-Name entry here (or moving shared config into and overriding only the extra manifest entry in this module).
