This pull request introduces improvements to the annotation APIs for MCP tool integrations and updates the library version. The main changes are focused on making annotation attributes optional and adding new configuration options for tool properties.

Annotation API improvements:

• Made the isRequired attribute optional (defaulting to false) in the McpToolProperty annotation, simplifying usage for optional properties.
• Added a new isArray attribute (defaulting to false) to the McpToolProperty annotation to specify if a property is an array, increasing flexibility in property definitions.

Dependency update:

• Updated the library version in pom.xml from 3.2.1 to 3.2.2, indicating a new release with these enhancements.
