fix issue #1154

AgentScope-Java Version

[The version of AgentScope-Java you are working on, e.g. 1.0.11, check your pom.xml dependency version or run mvn dependency:tree | grep agentscope-parent:pom(only mac/linux)]

Description

When using Spring Boot + A2A protocol, configuring server.servlet.context-path is ineffective, and the generated agent-card.json does not include the context-path in the URL.​

Checklist

Changes

Added a path field to DeploymentProperties.

AgentscopeA2aAutoConfiguration reads server.servlet.context-path and sets it to DeploymentProperties.

AgentScopeA2aServer uses the path when building the default Transport.

Added relevant unit tests.

Testing method

Start the service after configuring server.servlet.context-path=/api, then check whether the URL in .well-known/agent-card.json contains /api.

• Code has been formatted with mvn spotless:apply
• All tests are passing (mvn test)
• Javadoc comments are complete and follow project conventions
• Related documentation has been updated (e.g. links, examples, etc.)
• Code is ready for review
