fix(gemini): apply model execution config

[Zbhbb]

AgentScope-Java Version

Current main branch.

Description

Background

GeminiChatModel returned its SDK stream directly, so configured request timeout and retry settings were ignored even though other providers apply the shared execution wrapper.

Changes

• Apply ModelUtils.applyTimeoutAndRetry to Gemini response streams.
• Add timeout and retry coverage through the public stream() entry point.

Validation

• mvn -q -pl agentscope-extensions/agentscope-extensions-model/agentscope-extensions-model-gemini -am -Dtest=GeminiChatModelTest test
• mvn -q -T1 -pl agentscope-extensions/agentscope-extensions-model/agentscope-extensions-model-gemini -am verify

The full repository verify ran through its Java test phase, but the unrelated agentscope-builder step could not download npm 10.9.2 because the npm registry TLS handshake was terminated.

Checklist

• Code has been formatted with mvn spotless:apply rules
• Relevant tests are passing
• Javadoc follows existing conventions
• Documentation update is not needed
• Code is ready for review

Pull request overview

This PR ensures Gemini streaming calls honor the shared execution configuration (timeout + retry) by wrapping Gemini’s response Flux with the same ModelUtils.applyTimeoutAndRetry logic used by other providers, and adds unit tests to validate the behavior through the public stream() entry point.

Changes:

• Wrap GeminiChatModel streaming responses with ModelUtils.applyTimeoutAndRetry so timeout/retry configs are applied.
• Add tests verifying timeout enforcement and retry behavior when using stream().
