feat: add connectTimeout, requestTimeout, and logger options to client builder and transport

[stenalpjolly]

Summary

Adds connectTimeout(), requestTimeout(), and logger() options to McpToolboxClient.Builder (McpToolboxClientBuilder) and cascades these options down to BaseMcpTransport and all HttpMcpTransport version delegates (HttpMcpTransportV20241105, HttpMcpTransportV20250326, HttpMcpTransportV20250618, HttpMcpTransportV20251125).

Expectation & Implementation

• Expectation: Callers should be able to configure custom connection and request timeouts for HTTP requests made by the MCP client, as well as pass a custom java.util.logging.Logger instance for telemetry and logging.
• Implementation:
  • Added connectTimeout(), requestTimeout(), and logger() methods to McpToolboxClient.Builder interface and McpToolboxClientBuilder.
  • Added constructors to BaseMcpTransport, HttpMcpTransport, and all HttpMcpTransportV* delegate classes accepting connectTimeout, requestTimeout, and logger.
  • Configured HttpClient.Builder with the specified connectTimeout (defaulting to 10 seconds).
  • Configured HttpRequest.Builder with requestTimeout during listTools and invokeTool requests when specified.
  • Replaced static logger calls with activeLogger initialized from the provided logger or default class logger.

Test cases

• Added testInvokeTool_WithRequestTimeout in HttpMcpTransportTest to verify that instantiating HttpMcpTransport with custom request/connect timeouts successfully applies configurations across transport delegation and completes invokeTool calls cleanly.
• Executed mvn clean test jacoco:report -Dtest="*Test,!*E2ETest" -Dnet.bytebuddy.experimental=true verifying 129 tests pass cleanly across the SDK.

Acceptance criteria

• McpToolboxClient.Builder provides connectTimeout, requestTimeout, and logger configuration methods.
• Transport constructors accept and apply custom connection/request timeouts and logger.
• All unit and validation test suites pass cleanly with 100% backward compatibility for existing constructors.

Breaking changes

None. Secondary constructors are provided to maintain full backward compatibility for existing transport and client instantiations.
